We need to come up with a question involving the graph.
Very simple!
We can ask how much time in a day Cal spends for different activities.
We can say:
According to the graph, how much time of the day does Cal spend studying and sleeping?
answering this question:
[tex]\begin{gathered} \frac{1}{8}+\frac{1}{3} \\ =\frac{3(1)+8(1)}{3\times8} \\ =\frac{3+8}{24} \\ =\frac{11}{24} \end{gathered}[/tex]
