Suppose you want to enlarge a 4-inch by 6-inch photograph as much as possible so that it fits on a bulletin board that is 24 inches high. What will the width of the photograph be if the sides must remain in proportion?

a. What is the ratio of the height of the original photograph to the height of the enlargement?

b. What is that ratio in simplest form?

3 answers

Original photo = 4-1n. by 6-in.
enlarged photo = 16-in by 24-in.

a. Ratio = 6:24.

b. 6:24 = 1:4.
