Question
Harry made a scale drawing of the elementary school. The schoolyard, which is 154 meters long in real life, is 22 millimeters long in the drawing. What scale did Harry use?1 millimeter : meters
Solution
To find the scale that Harry used, you need to divide the real length by the length in the drawing.
Step 1: Identify the real length and the length in the drawing. The real length is 154 meters and the length in the drawing is 22 millimeters.
Step 2: Divide the real length by the length in the drawing.
154 meters / 22 millimeters = 7 meters per millimeter
So, Harry used a scale of 1 millimeter : 7 meters.
