RM 72 ÷ 3 = ?
| ? | ? | ? | ? | ? | |
| 3) | 7 | 2 | . | 0 | 0 |
整除 = bahagi tanpa baki
7 ÷ 3 = 2 余 1,落下 2 变 12,12 ÷ 3 = 4,余 0。ringgit 已经除完没有余数,sen 是 00,所以答案是 RM 24。
例子:RM 96 ÷ 4 → 9 ÷ 4 = 2 余 1 → 16 ÷ 4 = 4 → RM 24。
注意:余数是 0 的时候,sen 就是 .00,不用再除下去。
dividing without remainder = bahagi tanpa baki
7 ÷ 3 = 2 remainder 1; bring down 2 to make 12; 12 ÷ 3 = 4 with nothing left. The ringgit divide exactly and the sen are 00, so the answer is RM 24.
Example: RM 96 ÷ 4 → 9 ÷ 4 = 2 r 1 → 16 ÷ 4 = 4 → RM 24.
Watch out: when the remainder is 0, the sen are simply .00 and there is nothing more to divide.
RM 96.60 ÷ 4 = ?
| ? | ? | ? | ? | ? | |
| 4) | 9 | 6 | . | 6 | 0 |
带 sen 的被除数 = nilai yang ada sen
9 ÷ 4 = 2 余 1,落下 6 变 16,16 ÷ 4 = 4。到小数点,商也点上小数点。落下 6,6 ÷ 4 = 1 余 2;落下 0 变 20,20 ÷ 4 = 5。答案 RM 24.15。
例子:RM 48.80 ÷ 4 = RM 12.20。
注意:6 ÷ 4 有余数 2,要落下 0 变 20 继续除,不能停在 .1。
a dividend with sen = nilai yang ada sen
9 ÷ 4 = 2 remainder 1; bring down 6 to make 16; 16 ÷ 4 = 4. At the decimal point, place a point in the quotient too. Bring down 6; 6 ÷ 4 = 1 remainder 2; bring down 0 to make 20; 20 ÷ 4 = 5. The answer is RM 24.15.
Example: RM 48.80 ÷ 4 = RM 12.20.
Watch out: 6 ÷ 4 leaves 2, so bring down the 0 to make 20 and carry on; do not stop at .1.
RM 135 ÷ 6 = ?
| ? | ? | ? | ? | ? | ? | |
| 6) | 1 | 3 | 5 | . | 0 | 0 |
余数变 300 sen = baki jadi 300 sen
1 比 6 小,看 13:13 ÷ 6 = 2 余 1。落下 5 变 15,15 ÷ 6 = 2 余 3。余 RM 3 = 300 sen,点上小数点,落下 0 变 30,30 ÷ 6 = 5,落下 0,0 ÷ 6 = 0。答案 RM 22.50。
例子:RM 75 ÷ 6 → 7 ÷ 6 = 1 余 1 → 15 ÷ 6 = 2 余 3 → 30 ÷ 6 = 5 → RM 12.50。
注意:RM 22.05 是把 5 写到了 sen 的第二位,30 ÷ 6 的 5 应该在小数点后第一位。
remainder becoming 300 sen = baki jadi 300 sen
1 is less than 6, so look at 13: 13 ÷ 6 = 2 remainder 1. Bring down 5 to make 15; 15 ÷ 6 = 2 remainder 3. The RM 3 left is 300 sen, so place the point, bring down 0 to make 30, 30 ÷ 6 = 5, bring down 0, 0 ÷ 6 = 0. The answer is RM 22.50.
Example: RM 75 ÷ 6 → 7 ÷ 6 = 1 r 1 → 15 ÷ 6 = 2 r 3 → 30 ÷ 6 = 5 → RM 12.50.
Watch out: RM 22.05 puts the 5 in the second sen place; the 5 from 30 ÷ 6 belongs right after the point.
RM 7 834.40 ÷ 8 = ?
| ? | ? | ? | ? | ? | ? | ? | |
| 8) | 7 | 8 | 3 | 4 | . | 4 | 0 |
大数除以 8 = nilai besar bahagi 8
7 比 8 小,看 78:78 ÷ 8 = 9 余 6。落下 3 变 63,63 ÷ 8 = 7 余 7。落下 4 变 74,74 ÷ 8 = 9 余 2。点上小数点。落下 4 变 24,24 ÷ 8 = 3。落下 0,0 ÷ 8 = 0。答案 RM 979.30。
例子:RM 4 016.80 ÷ 8 = RM 502.10。
注意:RM 97.93 的小数点放错了,商的小数点要对着被除数的小数点。
a large amount divided by 8 = nilai besar bahagi 8
7 is less than 8, so look at 78: 78 ÷ 8 = 9 remainder 6. Bring down 3 to make 63; 63 ÷ 8 = 7 remainder 7. Bring down 4 to make 74; 74 ÷ 8 = 9 remainder 2. Place the point. Bring down 4 to make 24; 24 ÷ 8 = 3. Bring down 0; 0 ÷ 8 = 0. The answer is RM 979.30.
Example: RM 4 016.80 ÷ 8 = RM 502.10.
Watch out: RM 97.93 has the point in the wrong place; it must line up with the point in the dividend.
RM 5 270 ÷ 10 = ?
除以 10 = bahagi 10;移 1 位 = gerak 1 tempat
10 只有一个 0,所以小数点向左移 1 位:5 270.00 → 527.00。sen 是 00,答案写成 RM 527 就可以。这样的题不用长除法,数清楚除数有几个 0 就行。
例子:RM 860 ÷ 10 = RM 86;RM 9 100 ÷ 10 = RM 910。
注意:RM 52.70 移了两位,那是 ÷ 100 的答案。
dividing by 10 = bahagi 10; moving 1 place = gerak 1 tempat
10 has one zero, so the decimal point moves 1 place to the left: 5 270.00 → 527.00. The sen are 00, so the answer is simply RM 527. No long division is needed; just count the zeros in the divisor.
Example: RM 860 ÷ 10 = RM 86.
Watch out: RM 52.70 moves two places, which would be the answer for ÷ 100.
RM 1 950 ÷ 100 = ?
除以 100 后有 sen = bahagi 100, ada sen
100 有两个 0,小数点向左移 2 位:1 950.00 → 19.50。答案 RM 19.50,sen 是 50。
例子:RM 2 340 ÷ 100 = RM 23.40。
注意:移完后 50 sen 要写两位 .50,不要写成 .5。
sen appearing after ÷ 100 = bahagi 100, ada sen
100 has two zeros, so the decimal point moves 2 places to the left: 1 950.00 → 19.50. The answer is RM 19.50 with 50 sen.
Example: RM 2 340 ÷ 100 = RM 23.40.
Watch out: after moving, write the 50 sen as .50 with two digits, not .5.
RM 8 400 ÷ 1000 = ?
除以 1000 = bahagi 1000;移 3 位 = gerak 3 tempat
1000 有三个 0,小数点向左移 3 位:8 400.00 → 8.400,就是 RM 8.40。移完后末尾多出来的 0 可以去掉,但 sen 要保留两位。
例子:RM 6 500 ÷ 1000 = RM 6.50。
注意:RM 84 只移了两位,RM 0.84 移了四位,都不对。
dividing by 1000 = bahagi 1000; moving 3 places = gerak 3 tempat
1000 has three zeros, so the decimal point moves 3 places to the left: 8 400.00 → 8.400, which is RM 8.40.
Example: RM 6 500 ÷ 1000 = RM 6.50.
Watch out: RM 84 moves only two places and RM 0.84 moves four; neither is right.
