Question

Geraldo is trying to fit his encyclopedias on the shelf. Each encyclopedia is 2 1/4 inches thick. If Geraldo shelf is 2 1/4 feet wide how many encyclopedias will he be able to fit on his shelf?

Answer 1

12 Encyclopedias

Explanation:

The best way to solve this problem is to get everything into the smaller units.

2 1/4 feet = 24 inches + 3 inches = 27 inches for Geraldo's shelf length

To find how many encyclopedias can fit on Geraldo's shelf, we need to divide the total length by the thickness of each encyclopedia.

Number of Encyclopedias = Shelf Length / Thickness of 1 Encyclopedia

27 inches / 2.25 inches = 12 encyclopedias on Geraldo's shelf
