Solve the following problem. Rosalie 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.

Answer 1

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

Number of mornings in a week = 7

Time she exercises each morning = 2/5 hour

Total time spent exercising in a week = (2/5) x 7 = 14/5 hour

To convert this to a mixed number, we divide the numerator by the denominator:
14 ÷ 5 = 2 remainder 4

So, the answer is 2 4/5 hour.
