A blueprint shows a house with two fences. Fence A is 1 4/5 inches long in the blueprint and is to be 1 1/2 feet long. How long is fence B on the blueprint if fence B is set to be 5 feet long.

Answer 1

Answer: 6 inches for Fence B

1 4/5 inches = 9/5

1 1/2 feet = 3/2

9/5 times 5/6 = 3/2

multiply the number of inches by 5/6 to get number of feet

multiply the number of feet by 6/5 to get the number of inches

5 feet times 6/5 = 6 inches for Fence B

1 4/5 divided by 1 1/2 = (9/5)/(3/2) = 9/5 x 2/3 = 6/5. That's the ratio of feet to inches
