Question

An architect drew a 12 inch line to represent the length of a 30-foot room. If the line that represents the width of the room is 8 inches long, how wide is the actual room?

Answer 1

20 feet

Explanation:

12/30 = 8/x

(8 * 30/ 12 = 20

Answer 2

20 foot

Explanation:

12i=30f

So

2i=5f (divide both sides by 6)

So

8i=20f (multiply both sides by 4)
