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.

Question

9 1/5

2 4/5

7 2/5

14/5

Answer 1

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

Rosalie exercises for 2/5 of an hour every morning.

There are 7 mornings in a week.

We can multiply 2/5 by 7 to find the total exercise time in a week.

(2/5) * 7 = 14/5

Therefore, Rosalie spends 14/5 hours exercising in a week.

To convert this to a mixed number, divide the numerator (14) by the denominator (5).

14 ÷ 5 = 2 remainder 4

So, the answer is: 2 4/5.

Therefore, Rosalie spends 2 4/5 hours exercising in a week.
