Soalan 1 / 6Latihan tambahan
Apakah pecahan perseratus bagi petak jingga?
写分数 = tulis pecahan perseratus 数涂色的格子,整行算 10 格,再加零散的格。涂色的格数写在分子,全部 100 格写在分母。 例子:涂了 4 整行加 9 格 → 49/100。 注意:整行的数目写在十位,零散的格数写在个位,次序不要弄反。
write the fraction = tulis pecahan perseratus Count the coloured squares: each full row is 10, then add the extra squares. The coloured count is the numerator and the 100 squares make the denominator. Example: 4 full rows and 9 more squares → 49/100. Watch out: the number of full rows is the tens digit and the extra squares are the ones digit; keep that order.
Soalan 2 / 6Latihan tambahan
Bagaimanakah kita menyebut 0.81?
读小数 = sebut perpuluhan 小数点读作 perpuluhan,点后面的数字从左到右,一个数字读一次。 例子:0.62 读作 sifar perpuluhan enam dua。 注意:puluh 这个词不该出现在小数点后面的读法里。
saying a decimal = sebut perpuluhan The point is said perpuluhan, and the digits after it are said one at a time, starting with the digit nearest the point. Example: 0.62 is said sifar perpuluhan enam dua. Watch out: the word puluh should not appear in the part after the point.
Soalan 3 / 6Latihan tambahan
Berapakah petak perlu diwarnakan untuk menunjukkan 0.12?
涂多少格 = berapa petak 小数点后面两位数字合起来是几,就是几个百分之一,也就是要涂几格。先涂整行,再涂零散的格。 例子:0.47 → 涂 47 格(4 整行加 7 格)。 注意:问的是要涂的格数,不是剩下的白格。
how many squares = berapa petak The two digits after the point together tell how many hundredths there are, which is how many squares to colour. Colour full rows first, then the extra squares. Example: 0.47 → colour 47 squares (4 full rows and 7 more). Watch out: the question asks for squares to colour, not the white squares left over.
Soalan 4 / 6Latihan tambahan
Ali menyebut 0.40 sebagai “sifar perpuluhan empat puluh”. Apakah sebutan yang betul?
改正读法 = betulkan sebutan Ali 把小数点后的两位当成整数来读,所以错了。正确做法是逐个读出每个数字,后面的 0 也要读。 例子:0.20 读作 sifar perpuluhan dua sifar。 注意:0 在十分位还是百分位,读出来的次序完全不同。
correcting the reading = betulkan sebutan Ali read the two digits after the point as a whole number, which is wrong. Say each digit separately, including a final 0. Example: 0.20 is said sifar perpuluhan dua sifar. Watch out: a 0 in the tenths place and a 0 in the hundredths place are said in a different order.
Soalan 5 / 6Latihan tambahan
Ada 100 biji manik. 18 biji merah, yang lain kuning. Apakah perpuluhan bagi manik kuning?
求另一部分 = cari bahagian lain 先算黄色有几颗:全部 100 颗减去红色的颗数。再把这个数写成百分之几的小数。最后检查红加黄是不是 100。 例子:100 颗里蓝色 27 颗,其余白色 → 白色 73 颗 → 0.73。 注意:减法要退位,十位要减去借走的 1。
find the other part = cari bahagian lain First find the yellow beads: all 100 beads minus the red ones. Then write that number of hundredths as a decimal, and check that red plus yellow makes 100. Example: 27 of 100 are blue and the rest white → 73 white → 0.73. Watch out: regroup when subtracting and take the borrowed 1 from the tens.
Soalan 6 / 6Latihan tambahan
Dalam 0.57, digit 7 berada di tempat …
sa•persepuluhperseratus
0•57
数位 = nilai tempat 小数点左边是个位(sa);右边第一位是十分位(persepuluh),第二位是百分位(perseratus)。看数字离小数点有多远,就知道它在哪一位。 例子:0.39 里,3 在十分位,9 在百分位。 注意:小数点右边的位名都以 per 开头,不要和整数的十位、百位混淆。
place value = nilai tempat The ones place (sa) is left of the point. On the right, the first place is tenths (persepuluh) and the second is hundredths (perseratus). Count how far a digit sits from the point to name its place. Example: in 0.39 the 3 is in the tenths and the 9 is in the hundredths. Watch out: places after the point begin with per; do not mix them up with tens and hundreds.
