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.
To find the total time Rosalie spends exercising in a week, we need to multiply the time she exercises each day (2/5) by the number of days in a week. There are 7 days in a week.
2/5 * 7 = 14/5
To convert 14/5 to a mixed number, we divide 14 by 5.
14 ÷ 5 = 2 remainder 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 need to multiply the time she exercises each morning by the number of mornings in a week.
From the problem, we know that Rosalie exercises for 2/5 of an hour every morning. To find the number of hours she exercises in a week, we multiply 2/5 by 7 (the number of mornings in a week):
(2/5) * 7 = 14/5
To convert this to a mixed number, we divide the numerator (14) by the denominator (5) and write the quotient as the whole number and the remainder as the fraction:
14 ÷ 5 = 2 remainder 4
So the answer is 2 4/5. Rosalie spends 2 hours and 4/5 of an hour exercising in a week.
To solve this problem, we need to find out how much time Rosalie spends exercising in a week.
First, we need to calculate the time Rosalie spends exercising in one day. Given that Rosalie exercises for 2/5 of an hour every morning, we can multiply this fraction by 1 day:
(2/5) * 1 = 2/5
So, Rosalie exercises for 2/5 of an hour every day.
To find out how much time she spends exercising in a week, we need to multiply the daily exercise time by the number of days in a week, which is 7:
(2/5) * 7 = 14/5
Now, we have found that Rosalie exercises for 14/5 hours in a week. To convert this answer to a mixed number, we need to divide the numerator (14) by the denominator (5):
14 ÷ 5 = 2 remainder 4
Therefore, Rosalie spends 2 and 4/5 hours exercising in a week, which is the mixed number form.
