Question

Wendy drew a scale drawing of the auditorium. She used the scale 3 inches : 2 feet. The stage is 18 feet wide in real life. How wide is the stage in the drawing?

Answer 1

12 inches

Explanation:

`18 * (2 / 3)`

Answer 2

27 inches

Explanation:

We can use proportions to solve this problem. Put the drawing size over the real life size

3 inches x inches

------------- = -----------

2 ft 18 ft

Using cross products to solve

3 * 18 = 2 * x

54 = 2x

Divide each side by 2

54/2 =2x/2

27 =x

The stage should be 27 inches in the drawing
