Question

Zane measured a city and made a scale drawing. The scale of the drawing was 9 inches=3 yards. What scale factor does the drawing use?

Answer 1

1:12

Explanation:

To simplify 3 yards :

3 yd.* 36 in. = 108 inches

9:108 simplified :

9/9 = 1

108/9 = 12

So, the ratio for the scale factor is 1:12 :)
