Question

A model car is 8 inches long and 5.2

inches wide. If the actual car is 96 inches
long, how wide is the actual car?

Answer 1

use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.
