Question

The width of a poster board is 32 inches. Using scissors, you reduce the width of the poster board to 4 inches. What is the scale factor of the dilation?

8:1

2:4

1:8

8:32

Answer 1

Answer- 1:8

The original length of the board was 32 inches. Since it reduced we can divide 32 into 4. 32/4 is 8. This means that the scale factor of the dilation is 1:8. 32 is 8/1 of 4, so that means in ratio 1 whole is divided into 8 parts, hence 1:8.

I hope this helped and Good Luck <3!!!
