Question

During Christmas a book store sold 72 books. If the ratio of books to books marks sold was 9:2,how many bookmarks did the store sell

Answer 1

16

Explanation:

the 9 parts of the ratio is equivalent to 72 books

divide number of books by 9 to find one part of the ratio

`(72)/(9)` = 8 ← 1 part of the ratio

2 parts = 2 × 8 = 16 ← number of bookmarks sold
