Answer:
Answer key:
The change in the scale factor is 4/5.
12 / 15
12 ÷ 3 = 4
15 ÷ 3 = 5
4/5
Answer key: The change of scale means that 1 inch represented 4 feet, but now 1 inch represents 5 feet.
1 inch represents 4 feet which factors 12 feet.
4 cannot factor 15 feet.
5 can factor 15 feet.
1 inch would represent 5 feet then.
15 ÷ 5 = 3 inches
