Question

A banner measures 56  inches by 28  inches. A print is made that measures 8  inches by 4  inches. The scale factor is ________

Answer 1

Note that 8 inches is 1/7 of 56, and that 4 inches is also 1/7 of 28.

Thus, the scale factor is 1/7, going from full size to print size, or 7, going from print size to full size.
