Find the length of a picture frame whose width is 3 inches and whose proportions are the same as a 9-inch wide by 15-inch long picture frame.

The length is 5 inches.

Step-by-step explanation:

9/3=15/?

If you divide 9 by 3, you get 3 if you compare things you have to do the same on the other 'side'. So you do 15 divided by 3, the answer is 5.
