Scale Drawing: An enlarged or reduced drawing that is similar to the actual object. Scale: The ratio of the distance in the drawing to the corresponding actual distance. Example: The scale of a map is 1 inch: 20 miles. If the distance between two towns on a map is 8.5 inches, how far apart are the two towns? set up a proportio n and solve
