1 answer

To find the total time Rosalie spends exercising in a week, we need to multiply the time she spends exercising each morning by the number of mornings in a week.

We know Rosalie exercises for 2/5 of an hour each morning.

To convert this to a mixed number, we divide 2 by 5: 2 รท 5 = 0.4

So, Rosalie exercises for 0.4 hours each morning.

In a week, there are 7 mornings.

To find the total time she spends exercising in a week, we multiply the time spent each morning by the number of mornings in a week: 0.4 * 7 = 2.8

Therefore, Rosalie spends 2.8 hours exercising in a week.

Converting 2.8 to a mixed number, we have 2 4/5.
