Question

You finish washing 3/4 of your windows in an hour and a half. At that rate, how much longer will it take you to finish washing all the windows?

Answer 1

Let us set up a proportion!

0.75/1.5 = 1/x

Cross multiply.

0.75*x = .75x
1.5 *1 = 1.5

.75x/.75 = 1.5/.75
x=2

So our final answer: 2
