Soalan 1 / 14Latihan tambahan
RM 15.40 × 5 = ?
15.40
×5
?????
sen 乘后刚好整数 = hasil sen cukup ringgit 40 × 5 = 200 sen = RM 2,sen 写 00,进 2。15 × 5 = 75,加 2 得 77。答案 RM 77。 例子:RM 2.20 × 5 → 100 sen = RM 1,10 + 1 = RM 11。 注意:RM 75 是忘了进位的 2。
sen multiplying to whole ringgit = hasil sen cukup ringgit 40 × 5 = 200 sen = RM 2, so write 00 in the sen place and carry 2. 15 × 5 = 75, plus 2 gives 77. The answer is RM 77. Example: RM 2.20 × 5 → 100 sen = RM 1, then 10 + 1 = RM 11. Watch out: RM 75 leaves out the carried 2.

RM 3.70 × ? = RM 37
找乘数 = cari pendarab;移 1 位 = gerak 1 tempat 从 3.70 到 37,数字 3、7 没有变,只是小数点向右移了 1 位(3.70 → 37.0)。移 1 位就是乘 10,所以方框是 10。检查:RM 3.70 × 10 = RM 37,没错。 例子:RM 2.50 × □ = RM 25 → 移 1 位 → 10。 注意:数小数点移了几位,就知道乘的是 10、100 还是 1000。
finding the multiplier = cari pendarab From 3.70 to 37 the decimal point moved 1 place to the right (3.70 → 37.0), and 1 place means times 10. So the box is 10. Example: RM 2.50 × □ = RM 25 → 1 place → 10. Watch out: count how many places the point moved to know whether it is 10, 100 or 1000.
Soalan 7 / 14Latihan tambahan
RM 5.45 × ? = RM 545
移两位 = gerak dua tempat;乘 100 = darab 100 5.45 变成 545,数字 5、4、5 没有变,小数点向右移了 2 位。移 2 位就是乘 100,所以方框是 100。检查:RM 5.45 × 100 = RM 545,没错。 例子:RM 1.25 × □ = RM 125 → 100。 注意:数字 5、4、5 没有变,只有小数点的位置变了。
moving two places = gerak dua tempat 5.45 became 545, so the decimal point moved 2 places to the right, which means times 100. The box is 100. Example: RM 1.25 × □ = RM 125 → 100. Watch out: the digits 5, 4, 5 do not change; only the position of the point changes.
Soalan 8 / 14Latihan tambahan
RM 8.20 × 1000 = ?
乘 1000 补 0 = darab 1000, isi sifar 1000 有三个 0,小数点要向右移三位:8.20 只有两位小数,移到第三位时没有数字,就补一个 0,得 8200。答案 RM 8 200,千位用空格隔开。 例子:RM 6.40 × 1000 = RM 6 400。 注意:补的 0 放在最后,RM 8 020 是放错位置。
times 1000 with a filler zero = darab 1000, isi sifar Move the decimal point three places to the right: 8.20 has only two decimal digits, so the third place gets a 0, giving 8200. The answer is RM 8 200. Example: RM 6.40 × 1000 = RM 6 400. Watch out: the filler 0 goes at the end; RM 8 020 puts it in the wrong place.
