整体与一组 = satu benda dan satu kumpulan A 图是一样东西分成 5 等份，涂了 2 份；B 图是一组 5 个物件，涂了 2 个。两图分母都是 5、分子都是 2，所以都是 2/5。 例子：一块蛋糕切 6 等份拿走 5 份，或 6 个杯子蛋糕拿走 5 个，都是 5/6。 注意：只要“总份数”和“涂色份数”一样，分数就一样。

one thing or one group = satu benda dan satu kumpulan Picture A is one object cut into 5 equal parts with 2 shaded. Picture B is a group of 5 objects with 2 shaded. Both have denominator 5 and numerator 2, so both show 2/5. The pictures look different but the fraction is the same. Example: 5 of 6 equal cake slices, or 5 of 6 cupcakes, are both 5/6. Watch out: when the total parts and the shaded parts match, the fractions match.

必须等分 = mesti sama besar 把一样东西分成几份来写分数时，每一份要一样大。上面的长条分成 3 个相等的部分，涂 1 份就是 1/3。下面的长条虽然也有 3 份，但大小不同，涂的那一小份不能叫 1/3。 例子：一张纸对折两次得到 4 个一样大的长方形，每一个是 1/4。 注意：先检查是不是等分，再数份数。

equal parts are a must = mesti sama besar When one object is cut up to show a fraction, every part must be the same size. The top strip has 3 equal parts, so 1 shaded part is 1/3. The bottom strip also has 3 parts, but they are not equal, so its small shaded part cannot be called 1/3. Example: fold a sheet twice to get 4 equal rectangles; each one is 1/4. Watch out: check that the parts are equal before counting them.

圆形和一组物件 = bulatan dan sekumpulan objek 先看 A：数圆形一共分成几个相等的扇形，再数涂了几个。再看 B：数一共有几个球、涂了几个。把两边的“总数”和“涂色数”分别比较，就知道分数是否一样。 例子：圆形 8 等份涂 3 份，和 8 粒珠子涂 3 粒，都是 3/8。 注意：分母要用全部的数目，不能只数没涂的。

a circle and a group = bulatan dan sekumpulan objek Look at A: count the equal slices of the circle, then the shaded ones. Look at B: count all the balls, then the shaded ones. Compare the totals and the shaded counts of both pictures to decide whether the fractions match. Example: 3 of 8 equal circle slices and 3 of 8 beads are both 3/8. Watch out: the denominator uses all the parts, not just the unshaded ones.

分母不同 = penyebut berbeza 涂色的份数一样，不代表分数一样。分别数出 A 的长条一共几份、B 一共几个球，写出两个分数，再比较分母。分子相同时，分母不同，分数就不同。 例子：长条 6 等份涂 1 份是 1/6，7 颗珠子涂 1 颗是 1/7，两者不同。 注意：只看涂了几份是不够的，一定要看总份数。

different denominators = penyebut berbeza The same number of shaded parts does not always mean the same fraction. Count all the parts of strip A and all the balls in group B, write both fractions, then compare the denominators. With equal numerators, different denominators give different fractions. Example: 1 of 6 strip parts is 1/6 and 1 of 7 beads is 1/7; they are not the same. Watch out: counting the shaded parts alone is not enough; always check the total.

找出正确的三分之一 = cari satu pertiga 1/3 的意思是把一个整体分成 3 个一样大的部分，取其中 1 份。所以要找的图必须同时符合两点：刚好 3 份，而且每份一样大。 例子：一条丝带剪成 3 段一样长，其中 1 段是丝带的 1/3。 注意：份数对了还不够，每一份的大小也要检查。

spotting one third = cari satu pertiga 1/3 means one whole cut into 3 parts of the same size, with 1 part taken. So the right picture must pass two checks: exactly 3 parts, and every part the same size. Example: cut a ribbon into 3 equal lengths; one length is 1/3 of the ribbon. Watch out: having the right number of parts is not enough; check the sizes as well.
