S’pore Hokkien Huay Kuan 2007 PSLE Math Prelim Q44

Cynthia has 32 English and Chinese books. 4/5 of the English books and ¾ of the Chinese books are fiction books. She has a total of 25 fiction books. How many English fiction books are there?

Solution



5 units + 4 parts ----- 32 (Total books)
4 units + 3 parts ----- 25 (Fiction books)

Multiply "Total books" by 3 and
Multiply "Fiction books" by 4, we will have

15 units + 12 parts ----- 96
16 units + 12 parts ----- 100

From the above, we can see that
1 unit ---- 100 – 96 = 4

(English Fiction books) 4 units ---- 4 x 4 = 16

Answer: There are 16 English fiction books
