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?

Answer 1

The scale factor is found by dividing the new width by the original width:

Scale factor = new width / original width

In this case:

Scale factor = 4 inches / 32 inches

Scale factor = 1/8 or 0.125

Therefore, the scale factor of the dilation is 0.125 or 1/8.
