Question

A guitar shop has 19 acoustic guitars on display. This is 19% of the total number of guitars. What is the total number of guitars?

Answer 1

This is actually pretty easy. Let's find out how much 1% is worth first. 19 guitars = 19% therefore 19 ÷ 19 = [ 1 guitar = 1% ] The total number of guitars is going to be 100%, so if 1% × 100 = 100%, then 1 guitar × 100 = 100 guitars total.
