7 × 2 kg ÷ 4 = ? g
乘后除化成克 = darab, bahagi, jawapan dalam g
先算乘法得到总千克数,乘一千化成克,再除以四。用长除法时,每一位都要写商,遇到不够除的位要写零,不能跳过。算完可以用乘法检查:商乘除数应该等于被除数。
例子:5 × 2 kg ÷ 8 = 10 000 g ÷ 8 = 1 250 g。
注意:商中间的零不能漏写。
multiply, divide, answer in grams = darab, bahagi, jawapan dalam g
Multiply first to get the total kilograms, change it into grams (× 1 000) and divide by 4. In long division every place needs a quotient digit; write 0 where the division does not go, never skip it. Check by multiplying the quotient by the divisor.
Example: 5 × 2 kg ÷ 8 = 10 000 g ÷ 8 = 1 250 g.
Watch out: do not drop a zero in the middle of the quotient.
8 × 1 450 g ÷ 5 = ? kg ? g
克乘除后写成千克克 = tulis dalam kg dan g
先乘后除,得到的是克数。要写成几千克几克:千位以上的部分是千克,后三位是克;后三位如果是两位数,要保留占位的零来读。也可以先除后乘,看哪一种数字比较好算。
例子:6 × 1 150 g ÷ 3 = 2 × 1 150 g = 2 300 g = 2 kg 300 g。
注意:克的部分一定是三位数的位置,不能随意去掉零。
grams after × and ÷, written in kg and g = tulis dalam kg dan g
Multiply and then divide; the result is in grams. To write it in kilograms and grams, the thousands part is kilograms and the last three digits are grams, keeping any place-holder zero when you read them. You may divide first if that gives easier numbers.
Example: 6 × 1 150 g ÷ 3 = 2 × 1 150 g = 2 300 g = 2 kg 300 g.
Watch out: the grams always take three places, so zeros cannot simply be dropped.
10 kg 35 g ÷ 5 × 3 = ? kg ? g
带零的克 = gram dengan sifar
十千克三十五克化成克时,三十五只有两位数,百位要补零。用长除法除以五,商里可能出现零,要写进去;再乘三,最后写成几千克几克。
例子:8 kg 40 g ÷ 4 × 3 = 8 040 g ÷ 4 × 3 = 2 010 g × 3 = 6 030 g = 6 kg 30 g。
注意:商中间的零和克前面的零,都不能漏掉或多写。
grams with zeros = gram dengan sifar
When 10 kg 35 g is changed into grams, 35 has only two digits, so the hundreds place needs a zero. Divide by 5 with long division, writing any zero that appears in the quotient, then multiply by 3 and write the result in kg and g.
Example: 8 kg 40 g ÷ 4 × 3 = 8 040 g ÷ 4 × 3 = 2 010 g × 3 = 6 030 g = 6 kg 30 g.
Watch out: do not drop or add zeros, either inside the quotient or in front of the grams.
Sebuah lori membawa 6 kotak ikan. Setiap kotak berjisim 12 kg 500 g. Semua ikan dibahagi sama rata kepada 4 buah kedai. Berapakah jisim ikan bagi setiap kedai?
先求总数再平分 = cari jumlah, kemudian bahagi
六箱一样重的鱼,先用乘法求总质量;再平均分给四间店,用除法。可以先把每箱的质量化成克,乘六再除以四;最后把克换回几千克几克。
例子:4 箱各 7 kg 500 g,平分给 3 人 → 4 × 7 500 g ÷ 3 = 30 000 g ÷ 3 = 10 000 g = 10 kg。
注意:先乘后除,顺序跟着题意走。
find the total, then share = cari jumlah, kemudian bahagi
Six equal boxes of fish: multiply to find the total mass, then share it equally among four shops by dividing. Working in grams helps: change one box into grams, multiply by 6, divide by 4, and change the result back into kg and g.
Example: 4 boxes of 7 kg 500 g shared by 3 people → 4 × 7 500 g ÷ 3 = 30 000 g ÷ 3 = 10 000 g = 10 kg.
Watch out: follow the story: multiply first, then divide.
5 tan metrik = ? kg
公吨化千克 = tukar tan metrik kepada kg
一公吨等于一千千克,所以公吨化成千克就乘一千,等于在后面加三个零。反过来,千克化成公吨就除以一千。这个关系和千克化克、克化毫克一样,都是一千倍。
例子:7 tan metrik = 7 × 1 000 kg = 7 000 kg。
注意:乘一千是加三个零,不是一个或四个。
tonnes to kilograms = tukar tan metrik kepada kg
One metric tonne is 1 000 kg, so changing tonnes into kilograms means multiplying by 1 000, which puts three zeros on the end. Going the other way, divide kilograms by 1 000. It is the same step of one thousand as kilograms to grams or grams to milligrams.
Example: 7 tan metrik = 7 × 1 000 kg = 7 000 kg.
Watch out: multiplying by 1 000 adds three zeros, not one or four.
Sekampit beras 3 kg 640 g dibahagi sama rata kepada 8 bungkus. Mak Long mengambil 5 bungkus. Berapakah jisim beras yang diambil, dalam g?
先除后乘,答案用克 = bahagi, kemudian darab, jawapan dalam g
平均分成几份,再求其中几份的质量:先把质量化成克,除以总份数得到一份的质量;再乘拿走的份数。题目要克,算出来的克数就是答案,不用换回千克。
例子:2 kg 400 g 平分成 6 份,拿 4 份 → 2 400 g ÷ 6 = 400 g,400 g × 4 = 1 600 g。
注意:除以的是总份数,乘的是拿走的份数,两个数不要对调。
divide then multiply, answer in grams = bahagi, kemudian darab, jawapan dalam g
To find the mass of some of the equal packets, change the mass into grams, divide by the total number of packets to get one packet, then multiply by the number of packets taken. The question wants grams, so that number of grams is the answer; no need to change back to kilograms.
Example: 2 kg 400 g shared into 6 packets, 4 packets taken → 2 400 g ÷ 6 = 400 g, 400 g × 4 = 1 600 g.
Watch out: divide by the total number of packets and multiply by the number taken; do not swap them.
