找分母的倍数 = cari gandaan penyebut 这个分数已经是最简形式，所以方框里的数要能被分母整除。可以背一背分母的乘法表，看看哪个选项出现在表里；也可以用除法检查有没有余数。 例子：3/8 daripada 24 = 9，因为 24 ÷ 8 = 3，没有余数。 注意：能被分母的一个因数整除还不够，一定要能被整个分母整除。

find a multiple of the denominator = cari gandaan penyebut The fraction is already in simplest form, so the number in the box must divide exactly by the denominator. Say the times table of the denominator and see which choice appears, or divide and look for a remainder. Example: 3/8 of 24 = 9 because 24 ÷ 8 = 3 with no remainder. Watch out: dividing by a factor of the denominator is not enough; it must divide by the whole denominator.

列出范围内的倍数 = senaraikan gandaan 先从小到大列出分母的倍数，再圈出在题目范围里面的那些。每一组选项里的数都要全部符合，只要有一个不是倍数，这组就不对。 例子：1/4 daripada □ 是整数，□ 在 10 和 20 之间：12、16。 注意：“在 20 和 40 之间”不包括 20 和 40 本身；一组里有一个不能整除就不行。

list the multiples in the range = senaraikan gandaan List the multiples of the denominator in order, then circle those inside the range in the question. Every number in a choice must work; one number that is not a multiple makes the whole choice wrong. Example: 1/4 of □ is whole with □ between 10 and 20: 12 and 16. Watch out: between 20 and 40 does not include 20 and 40 themselves.

说明理由 = beri sebab 求几分之几 daripada 一个数，第一步是把数平均分成“分母”份。想一想：这一步能不能分得刚好？如果除完有余数，每份就不是整数，最后的结果也不是整数。 例子：2/9 daripada 30：30 ÷ 9 = 3 余 3，分不平均，所以不是整数；2/9 daripada 27 = 6 就是整数。 注意：判断会不会得到整数，要真的做一次除法看有没有余数，不要只凭数字的样子猜。

give a reason = beri sebab To find a fraction of a number, the first step is to share the number equally into as many groups as the denominator. Ask whether that step works exactly. If there is a remainder, each group is not whole, so the result is not whole. Example: 2/9 of 30: 30 ÷ 9 = 3 remainder 3, so it is not whole, but 2/9 of 27 = 6 is. Watch out: to decide whether the result is whole, actually do the division and look for a remainder; do not guess from how the numbers look.
