A photographer that is 3 inches wide by 5 inches long is being enlarged so that it is 12 inches long. How wide will the enlarged photo be?

We set up fractions. The numerator was 3 (which was the width). The denominator was 5 (which was the length). We set it equal to x/12 and cross multiplied and got 7.2.

12/5 = 2.4 times larger

3 x 2.4 = 7.2 inches wide
