Anna decided to start an exercise program. She kept track of how much she exercised each week. On Tuesday she took an aerobics class for 3/4 hour. On Thursday she went on a hike for 1 1/2 hours. On Saturday she played basketball for 3 1/4 hours. How many hours did she exercise in all last week?

Answer 1

3/4 + 1 1/2 + 3 1/4

3/4 + 6/4 + 13/4

22/4 = 11/2 = 5 1/2 hrs
