To find out how much time Rosalie spends exercising in a week, we need to find the product of the amount of time she exercises each day (2/5 of an hour) and the number of days in a week (7).
So, multiplying 2/5 by 7, we get: (2/5) * 7 = 14/5 hours.
Since 14 is divisible by 5, it can be written as a mixed number, which is 2 and 4/5.
Therefore, Rosalie spends 2 4/5 hours exercising in a week.
To find out how much time Rosalie spends exercising in a week, we need to multiply the time she spends exercising each morning (2/5 of an hour) by the number of mornings in a week (7).
2/5 * 7 = 14/5
Therefore, Rosalie spends 14/5 hours exercising in a week. This can be written as the mixed number 2 4/5 hours.
To solve this problem, we need to find the total time Rosalie spends exercising in a week. First, we need to find out how much time she exercises in a day.
Rosalie exercises for 2/5 of an hour every morning. This means she exercises for 2/5 hours per day.
Now, we need to calculate the total time she exercises in a week. Since there are 7 days in a week, we multiply the daily exercise time by 7 to get the weekly exercise time.
2/5 hours * 7 days = 14/5 hours
So, Rosalie spends 14/5 hours exercising in a week. To convert this answer to a mixed number, we divide the numerator (14) by the denominator (5).
14 รท 5 = 2 remainder 4
Therefore, the answer in mixed number format is 2 4/5 hours.
So, the correct response is: 2 4/5 hours
