Question

A scale drawing of a house uses a scale of 0.5 inches = 2 feet. What is the length, in inches, of a line on the scale drawing that represents an actual length of 5 feet?

Answer 1

Hi there!

0.5 inches on scale equals 2 feet in reality.

First we can determine the scale of 1 feet.
We only need to divide both sides by 2.

0.5 / 2 inches on scale equals 2 / 2 feet in reality
0.25 inches on scale equals 1 feet in reality.

To find our answer, 5feet in reality we must multiply both sides of our "equation" by 5.

0.25 × 5 inches on scale equals 1 × 5 feet in reality.
1.25 inches on scale equals 5 feet in reality.

Therefore the length of a line of the scale drawing that represents an actual length of 5 feet, has a length of 1.25 inches.

Answer 2

In this exercise we have to perform the conversion from inches to feet, so we find that:

$1.25 inches=5feets$

So we know that the conversion scale is equal to :

0.5 inches on scale equals 2 feet in reality.
