乘加法 = darab dan tambah 卡上是一个带分数,要写成假分数。可以用计算:整数乘分母,求出整数部分有几份,再加分子;也可以画图,每个整数分成九份,把涂色的份数全部数一遍。两种方法的结果要一样。 例子:1又7/9 → 1 × 9 + 7 = 16 → 16/9。 注意:乘法算错,后面的份数就会多几份或少几份,最好用画图再核对一次。
multiply and add = darab dan tambah The card shows a mixed number that must become an improper fraction. You can calculate: multiply the whole number by the denominator and add the numerator. Or draw each whole cut into ninths and count every shaded part. Both ways should agree. Example: 1 7/9: 1 × 9 + 7 = 16, so 16/9. Watch out: a slip in the multiplication gives a few parts too many or too few, so check with a drawing.

除法 = bahagi 卡上是一个假分数,要写成带分数。方法一:分子除以分母,商当整数,余数当分子。方法二:每次拿走八个八分之一(等于 1),一直拿到剩下的不够八份为止,拿了几次就是整数。 例子:27/8 → 27 ÷ 8 = 3 余 3 → 3又3/8。 注意:余数要比分母小;如果余数还大于或等于八,就表示商还可以再多 1。
divide = bahagi The card shows an improper fraction that must become a mixed number. Method 1: divide the numerator by the denominator; the quotient is the whole number and the remainder is the numerator. Method 2: keep taking away eight eighths (which is 1) until fewer than eight are left. Example: 27/8: 27 ÷ 8 = 3 remainder 3, so 3 3/8. Watch out: if the remainder is still 8 or more, the quotient can be one bigger.

Siti menukar 175 dengan cara bahagi dan mendapat 325. Adakah 175 dan 325 mewakili nilai yang sama?
两种写法比较 = banding dua bentuk 要判断一个假分数和一个带分数是不是同样大,先把它们换成同一种写法再比较:把带分数用“整数乘分母加分子”换成假分数,分母相同时比较分子就可以。 例子:比较 7/3 和 2又2/3:2又2/3 = 8/3,8/3 比 7/3 大,所以两者不相等。 注意:样子不同的两个数,大小可能相同,也可能不同,一定要换成同一种写法再比。
compare two forms = banding dua bentuk To decide whether an improper fraction and a mixed number are the same size, write them in the same form first. Change the mixed number into an improper fraction by multiplying and adding, then compare the numerators when the denominators match. Example: compare 7/3 and 2 2/3: 2 2/3 = 8/3, which is more than 7/3, so they are not equal. Watch out: two numbers that look different may or may not be equal, so always change them into one form first.
