Question

1. The floor of a building is 120 feet long

and 80 feet wide. A scale model of the
building has a length of 24 inches. What
is the width of the model?

Answer 1

Explanation:

120 ft relate to 24 inches.

120/80 must be the same ratio as 24/model width.

120/80 = 3/2

so,

24/width = 3/2

48/width = 3

48 = 3width

width = 48/3 = 16 inches
