Solve the following problem: Rosalie exercises for 2/5 of an hour every morning. How much time does she spend exercising in a week? Convert the answer to a mixed number.(1 point)
To find out how much time Rosalie spends exercising in a week, we need to multiply the time she exercises each day (2/5 of an hour) by the number of days in a week (7 days).
First, let's calculate the product of 2/5 and 7:
(2/5) x 7 = (2 x 7) / 5 = 14/5
Now, we can convert the improper fraction 14/5 into a mixed number:
14 รท 5 = 2 with a remainder of 4
The mixed number is 2 4/5.
Therefore, Rosalie spends 2 4/5 hours exercising in a week.
To find the amount of time Rosalie spends exercising in a week, we first need to determine how much time she spends exercising in a day.
Since there are 7 days in a week, we can multiply the exercise time per day by 7 to find the exercise time per week.
2/5 * 7 = 14/5 = 2 4/5
Therefore, Rosalie spends 2 and 4/5 hours exercising in a week.
To solve this problem, we need to find out how much time Rosalie spends exercising in a day, and then calculate the total time for a week.
First, to find out how much time Rosalie spends exercising in a day, we need to multiply the fraction 2/5 by the number of hours in a day, which is 24.
(2/5) * 24 = 48/5 = 9 3/5
So, Rosalie spends 9 3/5 hours exercising in a day.
To find the total time she spends exercising in a week, we multiply the time spent in a day by the number of days in a week, which is 7.
9 3/5 * 7 = (9 * 7) + (3/5 * 7) = 63 + 21/5 = 63 + 4 1/5 = 67 1/5
Therefore, Rosalie spends 67 1/5 hours exercising in a week.
