Question

A book shelf in a library is 3½ feet long. Each book on the shelf is⅝
inch wide. How many books will fit on the shelf?​

Answer 1

Answer:

1. as we know that 1 feet = 12 inches
2. therefore, 3½ feet = 42 inches
3. as each book takes 5/8 inches
4. therefore, 42 = number of books x (5/8)
5. number of books = (42 x 8)/5
6. number of books = 67.2
7. 67.2 books will fit.
