克除以 4 = gram bahagi 4 一位一位除：百位 8 ÷ 4 = 2，十位 4 ÷ 4 = 1，个位 0 ÷ 4 = 0，得 210 g。检查：210 × 4 = 840。 例子：960 g ÷ 3 = 320 g。 注意：个位的 0 也要写，21 g 漏掉了它。

grams divided by 4 = gram bahagi 4 Divide place by place: hundreds 8 ÷ 4 = 2, tens 4 ÷ 4 = 1, ones 0 ÷ 4 = 0, giving 210 g. Check: 210 × 4 = 840. Example: 960 g ÷ 3 = 320 g. Watch out: the 0 in the ones place must be written; 21 g leaves it out.

没有余数 = tiada baki 先除公斤：6 ÷ 3 = 2，刚好除尽，没有剩下的公斤要换成克。再除克：300 ÷ 3 = 100。所以每一份是 2 kg 100 g，公斤和克两栏都要除。 例子：8 kg 400 g ÷ 4 = 2 kg 100 g。 注意：2 kg 300 g 只除了公斤，克没有除。

no remainder = tiada baki Kilograms: 6 ÷ 3 = 2 exactly. Grams: 300 ÷ 3 = 100. The answer is 2 kg 100 g. Example: 8 kg 400 g ÷ 4 = 2 kg 100 g. Watch out: 2 kg 300 g divides the kilograms but forgets to divide the grams.

余 1 kg = baki 1 kg 5 ÷ 2 = 2 余 1。1 kg = 1 000 g，1 000 + 600 = 1 600 g，1 600 ÷ 2 = 800。答案 2 kg 800 g。 例子：3 kg 400 g ÷ 2 → 3 ÷ 2 = 1 余 1 → 1 400 ÷ 2 = 700 → 1 kg 700 g。 注意：2 kg 300 g 把余数丢了，只算 600 ÷ 2。

one kilogram left over = baki 1 kg 5 ÷ 2 = 2 remainder 1. 1 kg = 1 000 g, so 1 000 + 600 = 1 600 g and 1 600 ÷ 2 = 800. The answer is 2 kg 800 g. Example: 3 kg 400 g ÷ 2 → 3 ÷ 2 = 1 r 1 → 1 400 ÷ 2 = 700 → 1 kg 700 g. Watch out: 2 kg 300 g drops the remainder and only works out 600 ÷ 2.

余 2 kg = baki 2 kg 9 ÷ 7 = 1 余 2。2 kg = 2 × 1 000 = 2 000 g，2 000 + 100 = 2 100 g，2 100 ÷ 7 = 300。答案 1 kg 300 g。 例子：8 kg 500 g ÷ 5 → 8 ÷ 5 = 1 余 3 → 3 500 ÷ 5 = 700 → 1 kg 700 g。 注意：1 kg 30 g 是余数乘了 100：200 + 100 = 300，300 ÷ 7 也除不尽，就知道错了。

two kilograms left over = baki 2 kg 9 ÷ 7 = 1 remainder 2. 2 kg = 2 × 1 000 = 2 000 g, so 2 000 + 100 = 2 100 g and 2 100 ÷ 7 = 300. The answer is 1 kg 300 g. Example: 8 kg 500 g ÷ 5 → 8 ÷ 5 = 1 r 3 → 3 500 ÷ 5 = 700 → 1 kg 700 g. Watch out: 1 kg 30 g multiplies the remainder by 100; then 200 + 100 = 300, which 7 cannot even divide evenly, a sign that it is wrong.

净重再平分 = jisim bersih, kemudian bahagi 净重：3 kg 200 g − 200 g = 3 kg = 3 000 g。平均装 5 罐：3 000 ÷ 5 = 600 g。每罐 600 g。 例子：一盒饼干连盒 1 kg 100 g，盒子 100 g，分 4 份 → 1 000 ÷ 4 = 250 g。 注意：640 g 是连盒子一起除；3 kg 是只算了净重。

net mass, then share = jisim bersih, kemudian bahagi Net mass: 3 kg 200 g − 200 g = 3 kg = 3 000 g. Shared into 5 containers: 3 000 ÷ 5 = 600 g, so each container holds 600 g. Example: a tin of biscuits weighs 1 kg 100 g with the tin, the tin is 100 g, and 4 shares give 1 000 ÷ 4 = 250 g each. Watch out: 640 g divides the box as well, and 3 kg only finds the net mass.
