Ellie measured a campsite and made a scale drawing. The scale of the drawing was 6 inches = 3 feet. What is the drawing's scale factor? Simplify your answer and write it as a fraction.

1. Remember the measurements have to be the same units!
2. 3 feet * 12 = 36 inches
3. 6 inches

A scale factor is: New Measurement ÷ Old Measurement

36 inches / 6 inches = the gcf is six so divide the numerator and denominator by 6: 6/1
