Question

Thom has a scale model of his car. The scale is 1 inch = 12 inches. If the actual car has 16- inch wheels what size are the wheels on the scale model.

I don't know where to begin

Answer 1

Use a proportion. Cross multiply and solve for x.

1/12 = x/16

12x = 16

x = 16/12 = 1 1/4 inches
