Two lines are related by the scale 2 millimeters: 5 decimeters. How many times larger is the larger line?

A. 2.5

B. 25

C. 250

D. 2,500

Answer 1

.002 vs .5. So 0.5/0.002 is 250 times bigger

Answer 2

You have to write out the decimals properly. Milli is 10^-3 and deci is 10^-1. So 2 * 10^-3 is 0.002 and 5 * 10^-1 is 0.5.
