320 mℓ × 3 = ?
| mℓ | |
|---|---|
| 320 | |
| × | 3 |
| ? |
毫升乘一位数 = darab mℓ
个位 0 × 3 = 0,十位 2 × 3 = 6,百位 3 × 3 = 9,三个数位都没有进位,得 960 mℓ。960 不满 1 000,不用换成升。
例子:210 mℓ × 4 = 840 mℓ。
注意:323 mℓ 是把 3 加上去了,乘号不是加号。
multiplying millilitres = darab mℓ
0 × 3 = 0, 2 × 3 = 6 and 3 × 3 = 9, giving 960 mℓ. Since 960 is below 1 000, it stays in millilitres.
Example: 210 mℓ × 4 = 840 mℓ.
Watch out: 323 mℓ adds 3 instead of multiplying; a times sign is not a plus.
6 ℓ × 8 = ?
| ℓ | |
|---|---|
| 6 | |
| × | 8 |
| ? |
升乘一位数 = darab ℓ
只有升,没有毫升,用乘法表:6 × 8 = 48,答案 48 ℓ。不用进位,也不用换单位。
例子:4 ℓ × 9 = 36 ℓ。
注意:14 ℓ 是 6 + 8,42 ℓ 是 6 × 7,乘法表要背熟。
multiplying litres = darab ℓ
There are only litres, so use the times table: 6 × 8 = 48, and the answer is 48 ℓ. No millilitres are involved, so nothing needs to be carried or changed.
Example: 4 ℓ × 9 = 36 ℓ.
Watch out: 14 ℓ is 6 + 8 and 42 ℓ is 6 × 7; knowing the times tables well avoids both.
1 ℓ 230 mℓ × 3 = ?
| ℓ | mℓ | |
|---|---|---|
| 1 | 230 | |
| × | 3 | |
| ? | ? |
不进位乘法 = darab tanpa kumpul semula
mℓ:230 × 3 = 690;ℓ:1 × 3 = 3。答案 3 ℓ 690 mℓ。
例子:2 ℓ 110 mℓ × 4 = 8 ℓ 440 mℓ。
注意:1 ℓ 690 mℓ 忘了乘升,3 ℓ 230 mℓ 忘了乘毫升。
multiplying with no regrouping = darab tanpa kumpul semula
Millilitres: 230 × 3 = 690; litres: 1 × 3 = 3. The answer is 3 ℓ 690 mℓ.
Example: 2 ℓ 110 mℓ × 4 = 8 ℓ 440 mℓ.
Watch out: 1 ℓ 690 mℓ forgets to multiply the litres, and 3 ℓ 230 mℓ forgets the millilitres.
2 ℓ 350 mℓ × 4 = ?
| ℓ | mℓ | |
|---|---|---|
| 2 | 350 | |
| × | 4 | |
| ? | ? |
进 1 升 = bawa 1 ℓ
mℓ:350 × 4 = 1 400,写 400,进 1。ℓ:2 × 4 = 8,8 + 1 = 9。答案 9 ℓ 400 mℓ。
例子:3 ℓ 250 mℓ × 4 → 1 000 → 13 ℓ。
注意:8 ℓ 1 400 mℓ 的毫升超过 1 000,还要整理。
carrying one litre = bawa 1 ℓ
Millilitres: 350 × 4 = 1 400, so write 400 and carry 1. Litres: 2 × 4 = 8, and 8 + 1 = 9. The answer is 9 ℓ 400 mℓ.
Example: 3 ℓ 250 mℓ × 4 → 1 000 → 13 ℓ.
Watch out: 8 ℓ 1 400 mℓ still has more than 1 000 millilitres and must be tidied.
3 ℓ 125 mℓ × 8 = ?
| ℓ | mℓ | |
|---|---|---|
| 3 | 125 | |
| × | 8 | |
| ? | ? |
刚好一千 = tepat seribu
mℓ:125 × 8 = 1 000,刚好 1 ℓ,mℓ 栏写 0,进 1。ℓ:3 × 8 = 24,24 + 1 = 25。答案 25 ℓ。
例子:250 mℓ × 4 = 1 000 mℓ = 1 ℓ。
注意:24 ℓ 把刚好的 1 000 mℓ 丢掉了。
exactly a thousand = tepat seribu
Millilitres: 125 × 8 = 1 000, exactly 1 ℓ, so the millilitre column shows 0 and 1 is carried. Litres: 3 × 8 = 24, and 24 + 1 = 25. The answer is 25 ℓ.
Example: 250 mℓ × 4 = 1 000 mℓ = 1 ℓ.
Watch out: 24 ℓ throws away the full 1 000 mℓ.
750 mℓ × 6 = ?
| mℓ | |
|---|---|
| 750 | |
| × | 6 |
| ? |
积化成升和毫升 = tukar hasil darab
750 × 6 = 4 500 mℓ。4 500 = 4 000 + 500,所以是 4 ℓ 500 mℓ。
例子:600 mℓ × 5 = 3 000 mℓ = 3 ℓ。
注意:4 ℓ 50 mℓ 少了一个 0,500 不能写成 50。
changing the product = tukar hasil darab
750 × 6 = 4 500 mℓ. Since 4 500 = 4 000 + 500, the amount is 4 ℓ 500 mℓ.
Example: 600 mℓ × 5 = 3 000 mℓ = 3 ℓ.
Watch out: 4 ℓ 50 mℓ has lost a zero; 500 must not shrink to 50.
Sekotak jus oren berisi 1 ℓ 250 mℓ. Berapakah isi padu 5 kotak jus itu?
五盒果汁 = lima kotak jus
每盒一样多,用乘法:1 ℓ 250 mℓ × 5。mℓ:250 × 5 = 1 250,写 250,进 1。ℓ:1 × 5 + 1 = 6。答案 6 ℓ 250 mℓ。
例子:3 盒 1 ℓ 500 mℓ 的牛奶 → 4 ℓ 500 mℓ。
注意:5 ℓ 250 mℓ 少了进位的 1 ℓ。
five boxes of juice = lima kotak jus
Every box holds the same amount, so multiply: 1 ℓ 250 mℓ × 5. Millilitres: 250 × 5 = 1 250, so write 250 and carry 1. Litres: 1 × 5 + 1 = 6. The answer is 6 ℓ 250 mℓ.
Example: 3 cartons of milk with 1 ℓ 500 mℓ each → 4 ℓ 500 mℓ.
Watch out: 5 ℓ 250 mℓ is missing the carried litre.
2 ℓ 40 mℓ × 3 = ? mℓ
答案用毫升 = jawapan dalam mℓ
2 ℓ 40 mℓ = 2 040 mℓ(百位补 0)。2 040 × 3 = 6 120 mℓ。也可以先算 2 ℓ 40 mℓ × 3 = 6 ℓ 120 mℓ,再化成 6 120 mℓ。
例子:1 ℓ 20 mℓ × 4 = 4 080 mℓ。
注意:6 012 mℓ 是把 40 × 3 = 120 放错了位置。
an answer in millilitres = jawapan dalam mℓ
2 ℓ 40 mℓ = 2 040 mℓ, with a zero in the hundreds. 2 040 × 3 = 6 120 mℓ. You could also work out 2 ℓ 40 mℓ × 3 = 6 ℓ 120 mℓ first and then change it to 6 120 mℓ.
Example: 1 ℓ 20 mℓ × 4 = 4 080 mℓ.
Watch out: 6 012 mℓ puts the 120 from 40 × 3 in the wrong places.
