Question

The blueprint for Jessica’s new room has a scale that states every ½ inch is equal to 15 inches. If this blueprint shows the length of her new room to be 3 inches, what will be the actual length of her new room?

Answer 1

Her room is 90 inches.

Explanation:

1/2 x 6 = 3

If we multiply 1/2 by 6, then we must do the same to 15.

15 x 6 = 90.
