2 4/5 hours

Answer 1

To find the amount of time Rosalie spends exercising in a week, we need to multiply the amount of time she exercises each morning (2/5) by the number of days in a week (7):

2/5 * 7= 14/5

The answer is 14/5 hours. To convert this to a mixed number, we divide the numerator (14) by the denominator (5) to get the whole number part:

14 ÷ 5 = 2 (remainder 4)

The mixed number form is 2 4/5 hours.

57 yards

Answer 3

To find the total length that Sven swims, we need to multiply the number of laps (5) by the length of each lap (11 1/3):

5 * 11 1/3 = 55 5/3

The answer is 55 5/3 yards. To convert this to a mixed number, we divide the numerator (55) by the denominator (3) to get the whole number part:

55 ÷ 3 = 18 (remainder 1)

The mixed number form is 18 1/3 yards.
