To find the number of hours James trained each week, we need to find the product of the number of hours he trained each day (3 1/2) and the number of days in a week (7).
First, let's convert the mixed number 3 1/2 to an improper fraction.
3 1/2 = (7/2) + 1/2 = 7/2 + 2/2 = 9/2
Now we multiply the improper fraction 9/2 by 7 to get the total number of hours he trained each week.
(9/2) * 7 = (9*7) / 2 = 63/2
To reduce this fraction to lowest terms, we can divide both the numerator and denominator by their greatest common factor, which is 1.
63/2 = 63 ÷ 1 / 2 ÷ 1 = 63/2 = 31.5
Therefore, James trained for 31.5 hours each week.
Solve this problem. Reduce to lowest terms.
