Use the circle graph to determine how much hours per day becky spends on each activity?

There are 24 hours in a day.
Simply multiply the corresponding percentage to 24 hours to get its corresponding number of hours spent in a day.

School :         25 % x 24 = 6.00 hrs
Eating :          10 % x 24 = 2.40 hrs
Sleep :           40 % x 24 = 9.60 hrs
Homework:   10 %  x 24 = 2.40 hrs
Free time:      15 % x 24 = 3.60 hrs
Total             100%            24 hrs. 

The answer is 4.333...
