We must write step by step the problem dа ta:

Total hours: 15 1/3

Week 1: 6 1/4

Week 2: 4 2/3

Week 3: x

Let

x: number of practice hours in week 3.

We write the following equation:

(6 1/4) + (4 2/3) + x = 15 1/3

Clearing x:

x = (15 1/3) - (6 1/4) - (4 2/3)

x = 4.416666667

answer:

Rodrigo spend practicing during week 3:

4.416666667 hours
