Roberto wants to reduce a drawing that is 12 inches long by 9 wide. If his new drawing is 8 inches long, how wide will it be?

1.) ¹²/₉ = ⁴/₃

Simplify the fraction so it's easier to work with.

2.) ⁴/₃ = ⁸/x

Make ⁴/₃ equal to ⁸/x because since you want to find the new width, you need to make it equal to a new fraction.

3.) 4x = 24

Cross multiply.

4.) x = 6

Divide each side by 4.
