To find out how much time Rosalie spends exercising in a week, we need to multiply the amount of time she exercises each day by the number of days in a week.
Rosalie exercises for 2/5 of an hour every morning.
Let's multiply 2/5 by 7, the number of days in a week:
2/5 * 7 = 14/5
The answer is 14/5, which can be simplified to 2 4/5.
Therefore, Rosalie spends 2 4/5 hours exercising in a week.
