Latihan tambahan

年和月 = tahun dan bulan 一年从 Januari 数到 Disember，一共 12 个月，所以 1 tahun = 12 bulan。10 bulan 是以为时间也是十进的；7 bulan 是把一星期 7 天搬过来了。 例子：半年就是 12 的一半，6 bulan。 注意：月份只有 12 个，Disember 之后又回到 Januari，进入新的一年。

years and months = tahun dan bulan Counting from Januari to Disember gives 12 months, so 1 tahun = 12 bulan. 10 bulan wrongly assumes time works in tens, and 7 bulan borrows the 7 days of a week. Example: half a year is half of 12, which is 6 bulan. Watch out: there are only 12 months; after Disember the calendar returns to Januari in a new year.

两星期 = dua minggu 每星期 7 天，2 minggu 就是 7 + 7 = 14 hari，也就是 2 × 7。9 hari 是 2 + 7；20 hari 是把一星期当成 10 天。 例子：学校假期 2 minggu，就是放 14 天。 注意：看到 minggu，要想到 7，不是 10。

two weeks = dua minggu Each week has 7 days, so 2 minggu is 7 + 7 = 14 hari, which is also 2 × 7. 9 hari adds 2 and 7, and 20 hari treats a week as 10 days. Example: a school holiday of 2 minggu lasts 14 days. Watch out: when you see minggu, think of 7, not 10.

分钟化成秒 = minit kepada saat 1 minit 有 60 saat，5 minit 就是 5 × 60 = 300 saat。可以先算 5 × 6 = 30，再在后面加一个 0。500 saat 是把 1 minit 当成 100 saat；65 saat 是把 5 和 60 加起来。 例子：3 minit = 180 saat。 注意：分钟换秒要乘，不是加。

minutes into seconds = minit kepada saat 1 minit has 60 saat, so 5 minit is 5 × 60 = 300 saat. A quick way: 5 × 6 = 30, then put a 0 on the end. 500 saat treats a minute as 100 seconds, and 65 saat adds 5 and 60. Example: 3 minit = 180 saat. Watch out: changing minutes into seconds means multiplying, not adding.

小时化成分钟 = jam kepada minit 每小时 60 minit，3 jam 是 60 + 60 + 60 = 180 minit，也就是 3 × 60。300 minit 是把一小时当成 100 分钟；63 minit 是 60 + 3。 例子：一部 2 jam 的电影长 120 minit。 注意：jam 换 minit 用 60，这跟 minit 换 saat 一样。

hours into minutes = jam kepada minit Each hour has 60 minit, so 3 jam is 60 + 60 + 60 = 180 minit, or 3 × 60. 300 minit treats an hour as 100 minutes, and 63 minit is just 60 + 3. Example: a film that lasts 2 jam is 120 minit long. Watch out: hours to minutes uses 60, the same number as minutes to seconds.

年月化成月 = tahun dan bulan kepada bulan 先换年：2 tahun = 2 × 12 = 24 bulan，再加 3 bulan：24 + 3 = 27 bulan。23 bulan 是直接把数字写在一起；15 bulan 是只把 1 年算进去，12 + 3。 例子：1 tahun 5 bulan = 12 + 5 = 17 bulan。 注意：年后面有几年，就要乘几个 12。

years and months into months = tahun dan bulan kepada bulan Change the years first: 2 tahun = 2 × 12 = 24 bulan, then add the 3 bulan: 24 + 3 = 27 bulan. 23 bulan just writes the digits together, and 15 bulan counts only one year, 12 + 3. Example: 1 tahun 5 bulan = 12 + 5 = 17 bulan. Watch out: multiply 12 by the number of years, however many there are.

星期和天化成天 = minggu dan hari kepada hari 4 minggu = 4 × 7 = 28 hari，再加 2 hari，共 30 hari。42 hari 是把 4 和 2 写在一起；26 hari 是 28 减 2，方向反了。 例子：1 minggu 6 hari = 7 + 6 = 13 hari。 注意：后面的 2 hari 是“再多几天”，要加不是减。

weeks and days into days = minggu dan hari kepada hari 4 minggu = 4 × 7 = 28 hari, and adding 2 hari gives 30 hari. 42 hari puts the 4 and 2 side by side, and 26 hari subtracts the 2 instead of adding it. Example: 1 minggu 6 hari = 7 + 6 = 13 hari. Watch out: the extra 2 hari are added on, never taken away.

一小时多一点 = sejam lebih 1 jam 是 60 minit，再加 25 minit：60 + 25 = 85 minit。125 minit 是把 1 jam 当成 100 minit；65 minit 是把 25 当成 5，加错了。 例子：1 jam 10 minit = 70 minit。 注意：1 jam 后面加多少分钟，答案就是 60 加多少。

a little over an hour = sejam lebih 1 jam is 60 minit, so add the 25 minit: 60 + 25 = 85 minit. 125 minit treats an hour as 100 minutes, and 65 minit adds only 5 instead of 25. Example: 1 jam 10 minit = 70 minit. Watch out: for 1 jam and some minutes, the answer is 60 plus those minutes.

分秒化成秒 = minit dan saat kepada saat 2 minit = 2 × 60 = 120 saat，加 10 saat，得 130 saat。210 saat 是直接把 2 和 10 接起来；70 saat 是只算了 1 minit，60 + 10。 例子：跑步用了 1 minit 45 saat，就是 105 saat。 注意：分钟有几个，就要乘几个 60。

minutes and seconds into seconds = minit dan saat kepada saat 2 minit = 2 × 60 = 120 saat, and adding 10 saat gives 130 saat. 210 saat joins the 2 and 10 together, and 70 saat counts only one minute, 60 + 10. Example: a run of 1 minit 45 saat lasts 105 saat. Watch out: multiply 60 by however many minutes there are.

分钟化成小时和分钟 = minit kepada jam dan minit 75 minit 里拿出 60 minit 变成 1 jam，还剩 75 − 60 = 15 minit，所以是 1 jam 15 minit。7 jam 5 minit 是把 75 拆成 7 和 5；1 jam 25 minit 是以为 1 jam 是 50 minit。 例子：100 minit = 1 jam 40 minit。 注意：拆的时候一定是拿出 60，不是看十位数。

minutes into hours and minutes = minit kepada jam dan minit Take 60 minit out of 75 to make 1 jam, leaving 75 − 60 = 15 minit, so the answer is 1 jam 15 minit. 7 jam 5 minit splits 75 into its digits, and 1 jam 25 minit acts as if an hour were 50 minutes. Example: 100 minit = 1 jam 40 minit. Watch out: always take out 60, rather than reading off the tens digit.

秒化成分和秒 = saat kepada minit dan saat 100 saat 里有一个 60，拿出来变 1 minit，还剩 100 − 60 = 40 saat，所以是 1 minit 40 saat。10 minit 是把 100 当成十个十；2 minit 是 120 saat，多了 20 秒。 例子：90 saat = 1 minit 30 saat。 注意：100 saat 不等于 1 minit，因为 1 minit 只有 60 saat。

seconds into minutes and seconds = saat kepada minit dan saat 100 saat holds one 60, which becomes 1 minit, leaving 100 − 60 = 40 saat, so the answer is 1 minit 40 saat. 10 minit treats 100 as ten tens, and 2 minit is 120 seconds, 20 too many. Example: 90 saat = 1 minit 30 saat. Watch out: 100 saat is not 1 minit, because a minute has only 60 seconds.

月化成年和月 = bulan kepada tahun dan bulan 15 bulan 里拿出 12 bulan 变成 1 tahun，还剩 15 − 12 = 3 bulan，答案 1 tahun 3 bulan。1 tahun 5 bulan 是把 15 拆成 1 和 5；3 tahun 是 15 ÷ 5，跟年月没有关系。 例子：20 bulan = 1 tahun 8 bulan。 注意：月换年是一组 12，不是一组 10。

months into years and months = bulan kepada tahun dan bulan Take 12 bulan out of 15 to make 1 tahun, leaving 15 − 12 = 3 bulan, so the answer is 1 tahun 3 bulan. 1 tahun 5 bulan splits 15 into its digits, and 3 tahun comes from 15 ÷ 5, which has nothing to do with months. Example: 20 bulan = 1 tahun 8 bulan. Watch out: months group into years in twelves, not in tens.

天化成星期和天 = hari kepada minggu dan hari 23 hari 里有几个 7？3 × 7 = 21，还剩 23 − 21 = 2，所以是 3 minggu 2 hari。2 minggu 3 hari 是把 23 的两个数字倒过来读；4 minggu 1 hari 是 29 天，太多了。 例子：17 hari = 2 minggu 3 hari。 注意：剩下的天数一定少于 7，不然还能再凑一个星期。

days into weeks and days = hari kepada minggu dan hari How many 7s are in 23? 3 × 7 = 21, leaving 23 − 21 = 2, so the answer is 3 minggu 2 hari. 2 minggu 3 hari reads the two digits of 23 as the answer, and 4 minggu 1 hari is 29 days, too many. Example: 17 hari = 2 minggu 3 hari. Watch out: the days left over must be fewer than 7, or they would make another week.

加分钟满 60 = minit cukup 60 分钟相加：50 + 25 = 75 minit，满 60 就换成 1 jam，剩 15 minit。jam 变成 1 + 1 = 2。答案 2 jam 15 minit。1 jam 75 minit 没有换；2 jam 25 minit 是进了 1 jam 却只减了 50。 例子：1 jam 45 minit + 30 minit = 2 jam 15 minit。 注意：答案的分钟要少于 60 才算写好。

minutes reaching 60 = minit cukup 60 Add the minutes: 50 + 25 = 75 minit; 60 of them become 1 jam, leaving 15 minit, and the hours become 1 + 1 = 2. The answer is 2 jam 15 minit. 1 jam 75 minit never changes the 60, and 2 jam 25 minit adds an hour but takes away only 50 minutes. Example: 1 jam 45 minit + 30 minit = 2 jam 15 minit. Watch out: an answer is only finished when its minutes are below 60.

分秒相加 = tambah minit dan saat 秒：40 + 35 = 75 saat = 1 minit 15 saat，秒写 15，进 1 minit。分：3 + 1 + 1 = 5。答案 5 minit 15 saat。4 minit 75 saat 是秒满 60 没进位；5 minit 5 saat 是进位后剩下的秒算错了。 例子：2 minit 30 saat + 45 saat = 3 minit 15 saat。 注意：秒和分钟一样，满 60 进 1。

adding minutes and seconds = tambah minit dan saat Seconds: 40 + 35 = 75 saat = 1 minit 15 saat, so write 15 and carry 1 minute. Minutes: 3 + 1 + 1 = 5. The answer is 5 minit 15 saat. 4 minit 75 saat forgets to carry, and 5 minit 5 saat gets the leftover seconds wrong. Example: 2 minit 30 saat + 45 saat = 3 minit 15 saat. Watch out: seconds work like minutes; every 60 carries 1.

减时间要借位 = tolak masa dengan pinjam 10 − 45 不够减，向 jam 借 1 jam = 60 minit：10 + 60 = 70，70 − 45 = 25 minit。jam 被借走 1，剩 3，3 − 1 = 2。答案 2 jam 25 minit。3 jam 35 minit 是用 45 − 10 倒着减；3 jam 25 minit 是借了却没把 4 改成 3。 例子：3 jam 5 minit − 50 minit = 2 jam 15 minit。 注意：借了 1 jam，jam 那一栏就要少 1。

subtracting time with borrowing = tolak masa dengan pinjam 10 − 45 will not go, so borrow 1 jam = 60 minit: 10 + 60 = 70 and 70 − 45 = 25 minit. The hours lent 1 and become 3, and 3 − 1 = 2. The answer is 2 jam 25 minit. 3 jam 35 minit subtracts 45 − 10 backwards, and 3 jam 25 minit borrows but never changes 4 into 3. Example: 3 jam 5 minit − 50 minit = 2 jam 15 minit. Watch out: after borrowing an hour, the hours column is 1 less.

借 1 分钟是 60 秒 = pinjam 1 minit = 60 saat 20 − 50 不够，向分钟借 1：20 + 60 = 80，80 − 50 = 30 saat。分钟剩 4，4 − 2 = 2。答案 2 minit 30 saat。3 minit 30 saat 是 50 − 20 倒着减，又没借；2 minit 70 saat 是借成 100 saat，120 − 50 = 70，可是 1 minit 只有 60 saat。 例子：4 minit 10 saat − 1 minit 40 saat = 2 minit 30 saat。 注意：答案里的秒如果超过 59，一定是哪里错了。

borrowing 1 minute gives 60 seconds = pinjam 1 minit = 60 saat 20 − 50 will not go, so borrow 1 minute: 20 + 60 = 80 and 80 − 50 = 30 saat. The minutes drop to 4, and 4 − 2 = 2. The answer is 2 minit 30 saat. 3 minit 30 saat subtracts 50 − 20 backwards without borrowing, and 2 minit 70 saat borrows 100 seconds, 120 − 50 = 70, though a minute holds only 60. Example: 4 minit 10 saat − 1 minit 40 saat = 2 minit 30 saat. Watch out: if the seconds in an answer go above 59, something has gone wrong.

复名数乘一位数 = darab masa dengan satu digit 先乘分钟：35 × 3 = 105 minit，里面有一个 60，变成 1 jam，剩 45 minit。再乘小时：1 × 3 = 3，加进来的 1，是 4 jam。答案 4 jam 45 minit。3 jam 105 minit 是没有进位；4 jam 5 minit 是把 105 当成 1 百 0 十 5。 例子：1 jam 20 minit × 4 = 80 × 4 = 320 minit = 5 jam 20 minit。 注意：分钟乘出来超过 60，要拿 60 一组一组换成小时。

a mixed time times a one-digit number = darab masa dengan satu digit Multiply the minutes first: 35 × 3 = 105 minit, which holds one 60, so it becomes 1 jam and 45 minit. Then the hours: 1 × 3 = 3, plus the carried 1, is 4 jam. The answer is 4 jam 45 minit. 3 jam 105 minit never regroups, and 4 jam 5 minit treats 105 as 1 hundred and 5. Example: 1 jam 20 minit × 4 = 80 × 4 = 320 minit = 5 jam 20 minit. Watch out: when the minutes pass 60, change each group of 60 into an hour.

除时间的余数 = baki dalam bahagi masa 先除小时：5 ÷ 3 = 1 余 2 jam。余下的 2 jam 换成 120 minit，加原来的 15 minit 是 135 minit，135 ÷ 3 = 45 minit。答案 1 jam 45 minit。1 jam 5 minit 是把余下的 2 jam 丢掉了，只算 15 ÷ 3；2 jam 5 minit 是小时除错了。检查：1 jam 45 minit × 3 = 5 jam 15 minit。 例子：3 jam 20 minit ÷ 2 = 1 jam 40 minit。 注意：小时的余数要换成分钟，跟分钟合起来再除。

the remainder when dividing time = baki dalam bahagi masa Divide the hours first: 5 ÷ 3 = 1 remainder 2 jam. Change the 2 leftover hours into 120 minit, add the 15 minit to get 135 minit, and 135 ÷ 3 = 45 minit. The answer is 1 jam 45 minit. 1 jam 5 minit throws the leftover 2 hours away and only does 15 ÷ 3, and 2 jam 5 minit divides the hours wrongly. Check: 1 jam 45 minit × 3 = 5 jam 15 minit. Example: 3 jam 20 minit ÷ 2 = 1 jam 40 minit. Watch out: the leftover hours must be turned into minutes and joined with the minutes before dividing.

两个半小时 = dua jam setengah 2 jam = 120 minit，再加 30 minit，共 150 minit。230 minit 是把 2 和 30 接起来；90 minit 是只算 1 jam 加 30 minit。 例子：一场 2 jam 30 minit 的音乐会，长 150 minit。 注意：30 minit 就是半小时，所以 2 jam 30 minit 也叫两个半小时。

two and a half hours = dua jam setengah 2 jam = 120 minit, and adding 30 minit gives 150 minit. 230 minit joins the 2 and 30 together, and 90 minit counts only 1 hour plus 30 minutes. Example: a concert of 2 jam 30 minit lasts 150 minit. Watch out: 30 minit is half an hour, so 2 jam 30 minit is also called two and a half hours.

四分五秒 = 4 minit 5 saat 4 minit = 4 × 60 = 240 saat，再加 5 saat，得 245 saat。405 saat 是把 4 和 05 拼在一起；65 saat 是只算了 1 minit 再加 5。 例子：扫地用了 3 minit 20 saat，就是 200 saat。 注意：秒数只有一位时，也是直接加上去，不要变成 50。

four minutes five seconds = 4 minit 5 saat 4 minit = 4 × 60 = 240 saat, and adding 5 saat gives 245 saat. 405 saat glues the 4 and 05 together, and 65 saat counts only 1 minute plus 5. Example: sweeping the floor for 3 minit 20 saat takes 200 saat. Watch out: a one-digit number of seconds is simply added on; it does not become 50.

答案用分钟 = jawapan dalam minit 题目要答案写成分钟，所以先把 1 jam 20 minit 换成 60 + 20 = 80 minit，再加 45：45 + 80 = 125 minit。165 minit 是把 1 jam 当成 100 minit；65 minit 是漏了那 1 jam。 例子：30 minit + 1 jam 10 minit = 30 + 70 = 100 minit。 注意：单位不同的时间要先换成同一种单位再加。

the answer in minutes = jawapan dalam minit The answer must be in minutes, so first change 1 jam 20 minit into 60 + 20 = 80 minit, then add 45: 45 + 80 = 125 minit. 165 minit treats an hour as 100 minutes, and 65 minit leaves the hour out. Example: 30 minit + 1 jam 10 minit = 30 + 70 = 100 minit. Watch out: change times into the same unit before adding them.

整小时减分钟 = jam bulat tolak minit 3 jam 先换成 3 × 60 = 180 minit，再减 50：180 − 50 = 130 minit。250 minit 是把 3 jam 当成 300 minit；150 minit 是 180 − 30，减错了数。 例子：2 jam − 15 minit = 120 − 15 = 105 minit。 注意：小时和分钟不能直接相减，要先换成分钟。

whole hours minus minutes = jam bulat tolak minit First change 3 jam into 3 × 60 = 180 minit, then subtract 50: 180 − 50 = 130 minit. 250 minit treats 3 hours as 300 minutes, and 150 minit takes away 30 instead of 50. Example: 2 jam − 15 minit = 120 − 15 = 105 minit. Watch out: hours and minutes cannot be subtracted directly; change to minutes first.

乘完再换 = darab, kemudian tukar 25 × 6 = 150 minit。150 里有两个 60（120），还剩 30，所以是 2 jam 30 minit。1 jam 50 minit 是把 150 当成一百五十，拿 100 当 1 jam；2 jam 50 minit 是减掉 100 而不是 120。 例子：20 minit × 9 = 180 minit = 3 jam。 注意：分钟换小时，每 60 才是 1 jam。

multiply, then convert = darab, kemudian tukar 25 × 6 = 150 minit. 150 holds two 60s (120) with 30 left, so the answer is 2 jam 30 minit. 1 jam 50 minit takes 100 minutes as an hour, and 2 jam 50 minit takes away 100 instead of 120. Example: 20 minit × 9 = 180 minit = 3 jam. Watch out: when changing minutes into hours, only each 60 makes 1 jam.

小时平分 = bahagi jam sama banyak 2 jam 不够分给 4 份整小时，所以先换成分钟：2 × 60 = 120 minit，120 ÷ 4 = 30 minit。50 minit 是把 2 jam 当成 200 minit；15 minit 是把 1 jam 分成 4 份。检查：30 × 4 = 120。 例子：1 jam ÷ 3 = 60 ÷ 3 = 20 minit。 注意：2 ÷ 4 不够除时，先把小时换成分钟。

sharing hours equally = bahagi jam sama banyak 2 jam cannot be shared into 4 whole hours, so change to minutes: 2 × 60 = 120 minit, and 120 ÷ 4 = 30 minit. 50 minit treats 2 hours as 200 minutes, and 15 minit shares just 1 hour into 4. Check: 30 × 4 = 120. Example: 1 jam ÷ 3 = 60 ÷ 3 = 20 minit. Watch out: when 2 ÷ 4 will not go, turn the hours into minutes first.

三年四个月 = 3 tahun 4 bulan 3 tahun = 3 × 12 = 36 bulan，加 4 bulan，共 40 bulan。34 bulan 是数字直接拼起来；16 bulan 是只算了 1 年，12 + 4。 例子：弟弟 2 tahun 6 bulan 大，就是 30 bulan 大。 注意：先乘 12，再加剩下的月份。

three years four months = 3 tahun 4 bulan 3 tahun = 3 × 12 = 36 bulan, and adding 4 bulan gives 40 bulan. 34 bulan just joins the digits, and 16 bulan counts only one year, 12 + 4. Example: a little brother aged 2 tahun 6 bulan is 30 bulan old. Watch out: multiply by 12 first, then add the remaining months.

星期减天 = minggu tolak hari 单位不一样，不能 6 − 4。先换：6 minggu = 6 × 7 = 42 hari，再减 4 hari：42 − 4 = 38 hari。2 hari 是直接 6 − 4；46 hari 是把 4 加上去。 例子：3 minggu − 5 hari = 21 − 5 = 16 hari。 注意：减之前先看单位，单位不同先换。

weeks minus days = minggu tolak hari The units are different, so 6 − 4 is not allowed. Change first: 6 minggu = 6 × 7 = 42 hari, then subtract 4 hari: 42 − 4 = 38 hari. 2 hari does 6 − 4 directly, and 46 hari adds the 4 instead. Example: 3 minggu − 5 hari = 21 − 5 = 16 hari. Watch out: check the units before subtracting, and convert when they differ.

星期和天乘 2 = darab minggu dan hari 先换成天：1 minggu 3 hari = 7 + 3 = 10 hari，再乘 2：10 × 2 = 20 hari。26 hari 是把 1 minggu 3 hari 当成 13 天；16 hari 是只把 3 hari 乘 2 再加 10。 例子：2 minggu 1 hari × 3 = 15 × 3 = 45 hari。 注意：1 minggu 3 hari 不是 13 天，因为一星期只有 7 天。

weeks and days times 2 = darab minggu dan hari Change to days first: 1 minggu 3 hari = 7 + 3 = 10 hari, then multiply by 2: 10 × 2 = 20 hari. 26 hari treats 1 minggu 3 hari as 13 days, and 16 hari doubles only the 3 days and adds 10. Example: 2 minggu 1 hari × 3 = 15 × 3 = 45 hari. Watch out: 1 minggu 3 hari is not 13 days, because a week has only 7 days.

年平分成月 = bahagi tahun kepada bulan 2 ÷ 3 不够，先把 2 tahun 换成 2 × 12 = 24 bulan，24 ÷ 3 = 8 bulan。4 bulan 是只把 1 年分成 3 份；6 bulan 是 24 ÷ 4，除数看错了。检查：8 × 3 = 24。 例子：1 tahun ÷ 4 = 12 ÷ 4 = 3 bulan。 注意：答案要的是月，所以先全部换成月。

sharing years into months = bahagi tahun kepada bulan 2 ÷ 3 will not go, so first change 2 tahun into 2 × 12 = 24 bulan, and 24 ÷ 3 = 8 bulan. 4 bulan shares only one year into 3, and 6 bulan is 24 ÷ 4, which divides by the wrong number. Check: 8 × 3 = 24. Example: 1 tahun ÷ 4 = 12 ÷ 4 = 3 bulan. Watch out: the answer is wanted in months, so convert everything to months first.

三个分钟相加 = tambah tiga minit 40 + 35 + 50 = 125 minit。125 里有两个 60（120），剩 5，所以是 2 jam 5 minit。1 jam 25 minit 是把 100 当成 1 jam；2 jam 25 minit 是拿出两小时却只减了 100。 例子：30 minit + 45 minit + 15 minit = 90 minit = 1 jam 30 minit。 注意：总分钟超过 120 时，可以换出 2 jam。

adding three lots of minutes = tambah tiga minit 40 + 35 + 50 = 125 minit. 125 holds two 60s (120) with 5 left, so the answer is 2 jam 5 minit. 1 jam 25 minit treats 100 as an hour, and 2 jam 25 minit takes out two hours but subtracts only 100. Example: 30 minit + 45 minit + 15 minit = 90 minit = 1 jam 30 minit. Watch out: when the minutes pass 120, two whole hours can be taken out.

分钟余数换成秒 = tukar baki minit kepada saat 9 ÷ 4 = 2 余 1 minit。余下的 1 minit 换成 60 saat，加上 20 saat 是 80 saat，80 ÷ 4 = 20 saat。答案 2 minit 20 saat。2 minit 5 saat 是丢掉余数，只算 20 ÷ 4；2 minit 15 saat 是把余数当 40 秒。检查：2 minit 20 saat × 4 = 9 minit 20 saat。 例子：7 minit 30 saat ÷ 3 = 2 minit 30 saat。 注意：余下的分钟不能丢，要换成秒再除。

turning leftover minutes into seconds = tukar baki minit kepada saat 9 ÷ 4 = 2 remainder 1 minute. Change the leftover minute into 60 saat, add the 20 saat to get 80 saat, and 80 ÷ 4 = 20 saat. The answer is 2 minit 20 saat. 2 minit 5 saat drops the remainder and only does 20 ÷ 4, and 2 minit 15 saat treats the remainder as 40 seconds. Check: 2 minit 20 saat × 4 = 9 minit 20 saat. Example: 7 minit 30 saat ÷ 3 = 2 minit 30 saat. Watch out: a leftover minute must not be thrown away; turn it into seconds and divide.
