Luanne made a photocopy of a drawing of a rectangle. The original drawing was 4.5 inches wide and 6 inches long. The copy was 6.75 inches wide and 9 inches long. What was the scale factor for Luanne's copy?

The scale factor is:

6,75/4,5 = 9/6 = 1,5

So you divide the corresponding lengths and the ratio you get is the scale factor. Hope it helps!
