Instructions for a craft project say that the length of a piece of a red ribbon should be 7 1/8 inches less than the length of a piece of blue ribbon. If the red ribbon is 14 3/4 inches long, how long is the blue ribbon?

Step-by-step explanation:

Instructions for a craft project say that the length of a piece of a red ribbon should be 7 1/8 inches less than the length of a piece of blue ribbon. Converting 7 1/8 inches to improper fraction, it becomes

57/8 inches.

The red ribbon is 14 3/4 inches long. Converting 14 3/4 inches to improper fraction, it becomes

59/4 inches. Therefore, the length of the blue ribbon is

59/4 - 57/8 = (118 - 57) / 8

= 61/8 = 7 5/8 inches
