Michelle wants to run 3 miles to prepare for her next cross-country meet. She mapped out one route that is 3.25 miles long and another route that is 3.16 miles long. She uses rounding and finds that both routes are close to 3 miles long. Which explains how Michelle can choose the route that is closer to 3 miles?
A.


Look at the digits in the ones place. Since they are both 3, the 3.25-mile route is the same distance away from 3 miles as the 3.16-mile route.
B.


Look at the digits in the tenths place. Since 1 is less than 2, the 3.16-mile route is closer to 3 miles than the 3.25-mile route.
C.


Look at the digits in the hundredths place. Since 5 is less than 6, the 3.25-mile route is closer to 3 miles than the 3.16-mile route.
D.


Look at the digits in the thousandths place. Since they are both 0, the 3.25-mile route is the same distance away from 3 miles as the 3.16-mile route.
