Question

Mike had a photo made into a postage stamp the photo was 7 by 9.5 inches and the stamp was 1.4 by 1.9 inches what is the scale factor of dilation

Answer 1

The scale factor would be 0.2 because you have to divide the new stamp by the original so it would be 1.9/9.5=0.2 and same with 1.4/7=0.2
