Answer:
To find the percent of a number, you just need to convert the percent into a decimal (move the decimal over to the right 2 places) and multiply by 24 hours.
Sleep: 0.40 x 24 = 9.6 hours
School: 0.25 x 24 = 6 hours
Homework: 0.10 x 24 = 2.4 hours
Free Time: 0.15 x 24 = 3.6 hours
Eating: 0.10 x 24 = 2.4 hours
Hope this helps!
