Simply add the fractions 3%2F5, 1%2F2, and 3%2F4 to get your total time.


If you need help adding then here's how you add them:


3%2F5%2B1%2F2%2B3%2F4 Start with the given expression.


12%2F20%2B1%2F2%2B3%2F4 Multiply the first fraction by 4%2F4


12%2F20%2B10%2F20%2B3%2F4 Multiply the second fraction by 2%2F2


12%2F20%2B10%2F20%2B15%2F20 Multiply the third fraction by 5%2F5


%2812%2B10%2B15%29%2F20 Combine the fractions.


37%2F20 Add


So she exercised a total of 37%2F20 of an hour. Note: this means that she exercised for total of 111 minutes.
