Question

A magazine contains 80 pages of advertisements. This represents 64% of the total pages in the magazine. How many total pages are in the magazine?

Answer 1

125 pages

Explanation:

Since 80 is 64% of unknown x we can write the equation 80/x=64/100. Now cross multiply to get 8000=64x. Divide both sides by 64 to get 125=x.
