Rodrigo practiced playing the guitar for 15 1/3 hours over the past 3 weeks. He practiced for 6 1/4 hours during the first week and 4 2/3 hours during the second week. How much time did Rodrigo spend practicing during the third week? Use the numbers and symbols to write an equation that represents the problem. Then solve the equation.

Answer 1

Add up the sum and divide.

Practice Chart
1st Week: 6.25 Hours
2nd Week: 4.66 Hours
3rd Week: 15.33 - (1st Week + 2nd Week)

Solve:
6 1/4 + 4 2/3 = 10 8/12 or 10 2/3

15 1/3 - 10 2/3
14 4/3 - 10 2/3
4 2/3 hours practiced third week

Hope this helps!
