Answer 1

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
