A photo that is 2 in. wide is used to produce a poster that is 3 ft wide. What is the ratio of the width of the poster to the width of the photo?

one inch to 18 inches.

Explanation:

ok so. 3 feet is 36 inches, and your looking for whats called the unit rate, which is the ratio of one to one. so, divide 2 inches by 2 to get 1, and because you divided 2, you need to divide 36 as well, giving you 18. hope this helps
