Question

Noah has a collection of 2,500 stamps. Of the stamps in Noah’s collection, 30% show U.S. presidents, 45% show animals, and the rest show famous athletes. How many stamps in Noah’s collection show famous athletes?

Answer 1

Based on the total amount of stamps that Noah has, we can calculate that those showing famous athletes number 625 stamps.

The percentage that shows famous athletes is:

= 100% - U.S. Presidents - animals

= 100% - 30% - 45%

= 25%

With a collection of 2,500 stamps, the number that is for famous athletes is:

= 2,500 x 25%

= 625 stamps

In conclusion, 625 stamps show famous athletes.
