Question

A garage floor measures 150 feet by 120 feet. A scale drawing

of the floor on grid paper uses a scale of 1 unit : 15 feet. What
are the dimensions of the drawing?

Answer 1

It's a simple matter of dividing I think.

150/15 = 10 (units)
120/15 = 8 (units)

The dimensions of the drawing would be 10 units by 8 units.
