Unit 3
Akal Pintar
Ibu memotong kek kepada suku. Farah mengumpulkan 7 keping kek yang setiap satu 14.
Tulis jumlah kepingan itu sebagai pecahan tak wajar dan sebagai nombor bercampur.
几份几分之一 = beberapa bahagian yang sama
每块蛋糕是 1/4，7 块就是 7 个 1/4。我们要写出这个数量的假分数和带分数，并用图来说明为什么。
例子：5 块 1/3 → 5/3 → 1又2/3。
注意：每块的大小要一样，才能这样数。
several equal parts = beberapa bahagian yang sama
Each piece of cake is 1/4, so 7 pieces are 7 quarters. We write this amount as an improper fraction and as a mixed number, and show why with a picture.
Example: 5 pieces of 1/3 make 5/3, which is 1 2/3.
Watch out: every piece must be the same size for this to work.

Kira kepingan dan kumpulkan
7 × 14
7 keping 14 = 74 = 134
用图说明 = tunjukkan dengan gambar
7 块 1/4 放在一起：4 块拼成一个完整的蛋糕，就是 1；剩下 3 块是 3/4。所以 7 个 1/4 = 7/4 = 1又3/4。
例子：6 块 1/5 = 6/5 = 1又1/5。
注意：假分数的分子就是块数，分母就是每块的分母。
show it with a picture = tunjukkan dengan gambar
Put the 7 quarter pieces together: 4 of them make a whole cake, which is 1, and the other 3 are 3/4. So 7 quarters = 7/4 = 1 3/4.
Example: 6 pieces of 1/5 = 6/5 = 1 1/5.
Watch out: the numerator of the improper fraction is the number of pieces and the denominator is the size of each piece.
Cuba
11 keping, setiap satu 16. Apakah nombor bercampurnya?
拼成整数 = bentuk satu yang penuh
先把块数写成假分数：块数是分子，每块的大小是分母。再看几块可以拼成一个完整的 1，拼好几个整数，剩下的块数就写成分数。题目要的是带分数的写法。
例子：9 块 1/7 → 9/7 → 7 块拼成 1，剩 2 块 → 1又2/7。
注意：看清楚题目问的是假分数还是带分数，两个写法都对，但只有一个符合题目。
make a whole = bentuk satu yang penuh
First write the pieces as an improper fraction: the number of pieces is the numerator and the size of each piece is the denominator. Then see how many pieces make one whole; the pieces left over become the fraction part. The question wants the mixed number.
Example: 9 pieces of 1/7 make 9/7; 7 pieces make 1 and 2 are left, so 1 2/7.
Watch out: read whether the question asks for the improper fraction or the mixed number.
Ringkasan
Syabas!
74 = 134
