EXAMPLE 1 Comparing Metric Lengths Gerbils A Mongolian gerbil’s tail is about the same length as its body. A gerbil has a body length of centimeters and a tail length of centimeters. Which is longer, the body or the tail? 11 10.6
To answer the question above, picture the metric ruler below. The tail length, centimeters, is to the left of the body length, 11 centimeters. 10.6 EXAMPLE 1 Comparing Metric Lengths Gerbils A Mongolian gerbil’s tail is about the same length as its body. A gerbil has a body length of centimeters and a tail length of centimeters. Which is longer, the body or the tail? 11 10.6
