Question

Mr. Johnston needs a shelf to hold a set of textbooks. Each book is 3 3 4 cm wide. How many books will fit on an 86 cm wide shelf?

Please help

Answer 1

Answer: 23 books

Explanation:

Given Data:

Width of shelf = 86cm

Width of each book = 3 3/4 cm.

Therefore:

3 3/4cm = 3.75cm

To get how many books would fit into the shelf

= width of shelf / width of book

= 86cm / 3.75 cm

= 22.9 ≈ 23books

So 23 books would fit into the shelf

Answer 2

So it will contain the 25 books

Explanation:

Each book is 3.34 cm wide.

Total width if shelf is 86 cm

The number of books it will contain = 86/3.34

= 25.748 books

So it will contain the 25 books
