Question

Convert 100 centimeters to meters. (The conversion factor is 100 centimeter/meter.)

A. 1 meter
B. 100 meters
C. None Of These
D. 100 meters

Answer 1

A. 1 meter

Explanation:

When you convert, you use the conversion factor to do this. You multiply the conversion factor to the value you are converting. Since you are converting the centimeters to meters, when you use the conversion factor, you put the value of centimeters below. (The trick is, when you want to cancel out a unit, you put the same unit in the conversion factor in the opposite end of the fraction, which would be below)

`100cm*(1m)/(100cm)\\\\You\;cancel\;out\;the\;cm\\\\(100*1m)/(100)=(100m)/(100) = 1m`
