9 1/5 hours
9 Start Fraction 1 over 5 End Fraction hours
7 2/5 hours
7 Start Fraction 2 over 5 End Fraction hours
14/5 hours
Start Fraction 14 over 5 End Fraction hours
2 4/5 hours
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.
Sven swims 5 laps in a pool 11 1/3 yards long. What total length does he swim? Convert the answer to a mixed number.(1 point)

170/3 yards
Start Fraction 170 over 3 End Fraction yards
56 2/3 yards

57 yards
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.
