Answer:
16 hours
Step-by-step explanation:
Given:
- Time Mary spends on math homework per week: 2 2/3 hours
- Time Mary spends on art homework per week: 3 1/3 hours
Therefore, time spent on both homeworks over 4 weeks:
= 4 × (math homework + art homework )
[tex]=4(2 \frac23+1\frac13)[/tex]
[tex]=4\left(\dfrac83+\dfrac43\right)[/tex]
[tex]=4\left(\dfrac{12}3\right)[/tex]
[tex]=4(4)[/tex]
[tex]=16 \textsf{ hours}[/tex]
