Sophie made a scale drawing of a neighborhood park. The scale she used was 7 inches = 1 yard. What scale factor does the drawing use?
Simplify your answer and write it as a fraction.
The scale factor is the ratio of the length in the drawing to the actual length. In this case, 7 inches on the drawing represents 1 yard in reality.
The scale factor can be simplified by converting both measurements to the same unit:
1 yard = 36 inches
So, the scale factor can be simplified to:
7 inches / 36 inches = 7/36
Therefore, the scale factor of the drawing is 7/36.
