A certain blueprint shows two fences. Fence A is 1 1/2 yards long but is 1 7/8 inches long on the blueprint. What is the unit rate for inches per yard on this blueprint? If fence B is 4 yards long, how long is fence B on the blueprint?

Unit rate = 1.25 inches per yard

Length of fence B on the blueprint = 5 inches

Step-by-step explanation:

We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.

This means it's 1.2 yards long but 1.5 inches on the blueprint.

Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard

fence B is 4 yards long.

Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.
