A billboard is 4.0 meters by 2.5 meters. A scale diagram of the billboard must fit in a space that is 15 centimeters by 12 centimeters. Write a reasonable scale for the scale diagram.

Answer 1

15cm:4m is a scale of .0375
12cm:2.5m is a scale of .0480

So, use the smaller scale if it must all fit.
