Hello,

There are 24 hours in a day. If 25% of your day is spent at school, then you spent (24)(0.25) = 6 hours at school.

If 8% of your day is spent eating, then you spent (24)(0.08) = 1.92 hours eating.

Together, this is 6 + 1.92 = 7.92 hours ≈ 7.9 hours spent at school and eating in one day.

Hope this helps!
