A tire impression left in the mud at a crime scene was 8.7 inches wide. How many centimeters is that?

Answer 1

The answer is #22.098# #cm#.

Ascertain that you have the right ratio by applying the multiply by one method:

#8.7 Inch *(2.54 cm)/(1 Inch)=22.098# #cm#

We have the inches cancelling out and #cm# remaining in the numerator, so the units are correct.

This is multiplying by 1 because we are multiplying by 2 things that are equal, that is, #2.54# #cm=1# inch. You need to put the units that you want into the numerator and the units you want to cancel out in the denominator.
