Exercise 13 Page 315

Identify the conversion factor between centimeters and meters.

80cm=0.8m

Practice makes perfect
We want to complete the given conversion. 80cm= m Let's identify the conversion rate between centimeters (cm) and meters (m). 100cm=1m This means that the conversion factor between centimeters and meters can be expressed by the following fraction. 1m/100cm Now, we want to convert 80 centimeters to meters. Let's use dimensional analysis to do this. We will multiply the factor by 80cm and divide out common units. Let's do this!
80cm* 1m/100cm
80cm* 1m/100cm
80cm* 1m/100cm
80* 1m/100
80m/100
0.8m
We found that 80 centimeters are equal to 0.8 meters. Let's complete our conversion! 80cm&=0.8m Notice that, if we use an equivalent rate, we will end with the same solution.
