Problem
Joe practiced his trumpet 3/4 of an hour on Monday and 7/12 of an hour on Tuesday. How long did he practice altogether?
Result
b. 1 1/3 hours.
Solution
We need to turn the fractions into time first. This is done with division, multiplication, and addition.
Let's divide and multiply
3/4 · 60 = 45
7/12 ·60 = 35
Let's add
45 + 35 = 80
From here, 80 is 60 + 20 minutes, or 1 and 1/3
Hope this helped!
