number. (1 point)
091/ hours
O 14 hours
O 7/2/3 hours
O 2 hours
Rosalie exercises for 1/2 hour every morning. To find out how much time she spends exercising in a week, we multiply the time she spends exercising each day (1/2 hour) by the number of days in a week (7 days).
1/2 hour * 7 days = 7/2 hours
The answer is 7/2 hours, which is equivalent to 3 1/2 hours in mixed number form. So, Rosalie spends 3 1/2 hours exercising in a week.
