Question

The scale of a model house to the actual house is 1:150. If the actual house size is 40 feet high, how many feet tall is the model? (round your answer to the nearest tenth​

Answer 1

Answer: 0.3 feet

Work Shown:

(1 ft)/(150 ft) = (x ft)/(40 ft)

1/150 = x/40

1*40 = 150*x

40 = 150x

x = 40/150

x = 4/15

x = 0.2667 approximately

x = 0.3

Note: 0.3 ft = 0.3*12 = 3.6 inches
