5. Example 1 Convert Between Measurement Systems Convert 7.13 miles to kilometers. Round to the nearest hundredth if necessary. Since 1 mile  1.61 kilometers, multiply by Multiply by Divide out common units.  11.48 kmSimplify. Answer: So, 7.13 miles is approximately 11.48 kilometers.

6. Example 1 CYP A.98.21 B.37.89 C.9.82 D.3.79 Convert 61 miles to kilometers. Round to the nearest hundredth if necessary.

7. Example 2 Convert 925.48 grams to pounds. Round to the nearest hundredth if necessary. Convert Between Measurement Systems  2.04 lbSimplify. Answer: So, 453.6 grams is approximately 2.04 pounds. Since 453.6 g  1 lb, multiply by Multiply by Divide out common units.

8. Example 2 CYP A.0.93 ft B.9.3 ft C.10.33 ft D.103.33 ft Convert 31 meters to feet. Round to the nearest hundredth if necessary.

9. Example 3 Convert Between Systems MOUNTAINS Pike’s Peak in Colorado rises to a height of about 4,233 meters above sea level. About how many feet high is Pike’s Peak?  14,110 ftSimplify. Answer: So, 4,233 meters is approximately 14,110 feet. Since 1 foot  0.30 m, use the ratio Multiply by Divide out common units.
