厘米长除法 = bahagi panjang dalam cm
百位 8 ÷ 4 = 2;十位 5 ÷ 4 = 1 余 1;余 1 和个位 2 合成 12,12 ÷ 4 = 3。答案 213 cm。
例子:936 cm ÷ 3 = 312 cm。
注意:203 cm 漏了十位的 1;231 cm 是把商的数字写反了。
long division in centimetres = bahagi panjang dalam cm
Hundreds: 8 ÷ 4 = 2. Tens: 5 ÷ 4 = 1 remainder 1. The remainder joins the ones to make 12, and 12 ÷ 4 = 3. The answer is 213 cm.
Example: 936 cm ÷ 3 = 312 cm.
Watch out: 203 cm misses the 1 in the tens, and 231 cm writes the digits of the answer in the wrong order.
96 m ÷ 8 = ?

米数除法 = bahagi meter
十位 9 ÷ 8 = 1 余 1;余 1 和个位 6 合成 16,16 ÷ 8 = 2。答案 12 m。也可以想:8 × 12 = 96。
例子:84 m ÷ 7 = 12 m。
注意:88 m 是用减法 96 − 8;11 m 是把余数忘了。
dividing metres = bahagi meter
Tens: 9 ÷ 8 = 1 remainder 1. The remainder joins the 6 to make 16, and 16 ÷ 8 = 2. The answer is 12 m. You can also think: 8 × 12 = 96.
Example: 84 m ÷ 7 = 12 m.
Watch out: 88 m comes from subtracting 96 − 8, and 11 m forgets the remainder.
6 m 48 cm ÷ 2 = ?
| m | cm | |

| ? | ? | |
| 2) | 6 | 48 |
两栏都能除尽 = kedua-dua lajur boleh dibahagi
m:6 ÷ 2 = 3,没有余数。cm:48 ÷ 2 = 24。答案 3 m 24 cm。
例子:8 m 60 cm ÷ 2 = 4 m 30 cm。
注意:3 m 48 cm 只除了 m;6 m 24 cm 只除了 cm,两栏都要除。
both columns divide evenly = kedua-dua lajur boleh dibahagi
Metres: 6 ÷ 2 = 3 with nothing left over. Centimetres: 48 ÷ 2 = 24. The answer is 3 m 24 cm.
Example: 8 m 60 cm ÷ 2 = 4 m 30 cm.
Watch out: 3 m 48 cm divides only the metres and 6 m 24 cm divides only the cm; both columns must be divided.
7 m 35 cm ÷ 5 = ?
| m | cm | |
|---|---|---|
| ? | ? | |
| 5) | 7 | 35 |
余 2 米换 200 厘米 = baki 2 m jadi 200 cm
7 ÷ 5 = 1 余 2。余下 2 m = 200 cm,200 + 35 = 235 cm,235 ÷ 5 = 47。答案 1 m 47 cm。
例子:9 m 20 cm ÷ 4 → 9 ÷ 4 = 2 余 1 → 120 ÷ 4 = 30 → 2 m 30 cm。
注意:1 m 7 cm 丢了余数;1 m 11 cm 是把 2 m 当成 20 cm。
a 2 m remainder becomes 200 cm = baki 2 m jadi 200 cm
7 ÷ 5 = 1 remainder 2. The leftover 2 m is 200 cm; 200 + 35 = 235 cm and 235 ÷ 5 = 47. The answer is 1 m 47 cm.
Example: 9 m 20 cm ÷ 4 → 9 ÷ 4 = 2 r 1 → 120 ÷ 4 = 30 → 2 m 30 cm.
Watch out: 1 m 7 cm drops the remainder, and 1 m 11 cm treats the 2 m as only 20 cm.
9 m ÷ 4 = ?
| m | cm | |
|---|---|---|
| ? | ? | |
| 4) | 9 | 0 |
整米除不尽 = m bulat ada baki
9 ÷ 4 = 2 余 1。余下 1 m = 100 cm,100 ÷ 4 = 25 cm。答案 2 m 25 cm。
例子:5 m ÷ 2 = 2 m 50 cm。
注意:2 m 1 cm 是把余数 1 直接写成 1 cm;只写 2 m 是把余数丢掉了。
whole metres with a remainder = m bulat ada baki
9 ÷ 4 = 2 remainder 1. The leftover 1 m is 100 cm, and 100 ÷ 4 = 25 cm. The answer is 2 m 25 cm.
Example: 5 m ÷ 2 = 2 m 50 cm.
Watch out: 2 m 1 cm writes the remainder 1 straight down as 1 cm, and 2 m on its own throws the remainder away.
Ibu memotong kain 3 m 60 cm kepada 8 helai yang sama panjang. Berapakah panjang setiap helai?
剪布应用题 = masalah memotong kain
平均剪成 8 条,用除法。3 ÷ 8 不够除,把 3 m 60 cm 换成 360 cm,360 ÷ 8 = 45。每条 45 cm。
例子:2 m 40 cm 剪成 6 条 → 240 ÷ 6 = 40 cm。
注意:45 m 比整块布还长,一定不对;4 m 5 cm 也比 3 m 60 cm 长。
a cloth-cutting problem = masalah memotong kain
Cutting into 8 equal pieces means dividing. 3 ÷ 8 cannot be shared, so change 3 m 60 cm into 360 cm; 360 ÷ 8 = 45. Each piece is 45 cm.
Example: 2 m 40 cm cut into 6 pieces → 240 ÷ 6 = 40 cm.
Watch out: 45 m is longer than the whole cloth, so it cannot be right, and 4 m 5 cm is also longer than 3 m 60 cm.
