蛋糕和糕点 = kek dan kuih 蛋糕是一个整体，平分成几份、吃了几份，可以写成一个分数；糕点是一组物件，一共几个、吃了几个，也写成一个分数。把两个分数的分母和分子分别比较。 例子：西瓜切 10 等份吃 7 份，和 10 粒葡萄吃 7 粒，都是 7/10。 注意：糕点的分母是糕点的总数，不是剩下的个数。

cake and kuih = kek dan kuih The cake is one whole: count its equal pieces and the pieces eaten to write a fraction. The kuih are a group: count them all and the ones eaten to write another fraction. Then compare the two denominators and the two numerators. Example: 7 of 10 equal watermelon slices and 7 of 10 grapes are both 7/10. Watch out: the denominator for the kuih is how many there were at first, not how many are left.

圆形的分数 = pecahan bulatan 数一数圆形一共被分成几个相等的扇形，这是分母；再数涂了颜色的扇形，这是分子。 例子：圆形分 7 等份，涂 4 份 → 4/7。 注意：分母要数全部扇形，不是只数没涂色的扇形。

fraction of a circle = pecahan bulatan Count how many equal slices the circle is cut into; that is the denominator. Then count the shaded slices; that is the numerator. Example: a circle cut into 7 equal slices with 4 shaded → 4/7. Watch out: the denominator counts every slice, not only the unshaded slices.

长条和一组球 = jalur dan bola 先数 A 的长条一共几格、涂了几格，写成分数；再数 B 一共几个球、涂了几个，也写成分数。两边的总数和涂色数都相同，分数才相同。 例子：长条 9 格涂 2 格，和 9 个球涂 2 个，都是 2/9。 注意：7/3 把涂色的和没涂色的拿来比，不是分数的写法。

a strip and a group of balls = jalur dan bola Count the boxes of strip A and the shaded ones, and write a fraction. Do the same for the balls in group B. Only when both the totals and the shaded counts agree are the fractions the same. Example: 2 of 9 boxes on a strip and 2 of 9 balls are both 2/9. Watch out: 7/3 compares shaded with unshaded, which is not how a fraction is written.

不等分的纸 = kertas tidak sama besar 把一样东西写成分数之前，要先检查它是不是分成一样大的部分。“三分之一”的意思是：分成 3 个一样大的部分，取其中 1 份。读题时找出纸是怎样折的，再用这个规则判断。 例子：一块饼干掰成大小不同的 2 块，小的那块不是 1/2。 注意：只数份数、不看大小，就会答错。

paper folded unevenly = kertas tidak sama besar Before writing a fraction for one object, check that it is split into parts of the same size. One third means 3 parts of the same size with 1 part taken. Read how the paper was folded and judge it by this rule. Example: a biscuit snapped into 2 uneven pieces; the small piece is not 1/2. Watch out: counting the parts without checking their sizes leads to the wrong answer.

做出同样的分数 = buat pecahan yang sama 先把长条涂色的部分写成分数。珠子的总数就是新的分母；如果新的分母和长条的分母一样，要涂的珠子数就等于长条的分子。 例子：长条 6 格涂 1 格是 1/6 → 6 粒珠子也涂 1 粒。 注意：5 是没有涂色的数目，不是要涂的。

making the same fraction = buat pecahan yang sama First write the shaded part of the strip as a fraction. The number of beads is the new denominator; when it is the same as the strip's denominator, the beads to colour equal the strip's numerator. Example: 1 of 6 boxes on a strip is 1/6 → colour 1 of 6 beads. Watch out: 5 is the number left uncoloured, not the number to colour.
