钱的比例 = kadaran wang 先求一包的价钱，再乘以 10。 例子：2 包 RM6，1 包 RM3，9 包 RM27。 注意：先除后乘，第一步求出的“一包”的价钱还不是最后答案。

money proportion = kadaran wang Find the price of one packet, then multiply by 10. Example: 2 packets cost RM6, so 1 costs RM3 and 9 cost RM27. Watch out: divide first, then multiply; the price of one from the first step is not yet the final answer.

重量的比例 = kadaran jisim 先求一颗蛋的重量，再乘以 2。 例子：3 颗 150 克，1 颗 50 克。 注意：要的颗数比已知的少，答案应该比原来的总重量小。

mass proportion = kadaran jisim Find the mass of one egg, then multiply by 2. Example: 3 eggs weigh 150 g, so 1 egg is 50 g. Watch out: you want fewer eggs than you know about, so the answer should be smaller than the total you started with.

长度的比例 = kadaran panjang 先求一支吸管多长，再乘以 5。 例子：4 支共 40 厘米，1 支 10 厘米。 注意：答案的单位是厘米，算完以后可以想一想 5 支是不是比 6 支短一点。

length proportion = kadaran panjang Find the length of one straw, then multiply by 5. Example: 4 straws measure 40 cm, so 1 straw is 10 cm. Watch out: the answer is in centimetres; afterwards check that 5 straws come out a little shorter than 6.
