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?

27 inches

Step-by-step 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

yes. we do proportions in probabilities.
