there's 24 hours in a day so 24/100 = 0.24 < that is the percentage per hour first eating - %10. 0.24x10= 2.4hrs eating free time - 15% 0.24x15= 3.6hrs of free time homework - 10% 0.24x10 = 2.4hrs of homework school - 25% 0.24x25= 6hrs of school and sleeping = 40% 0.24x40=9.6hrs of sleep add them(hours) all up and you'll get 24!
multiply 24 by each of the percents
24x 10%=2.4 hrs HOMEWORK & EATING
24X 25%= 6 hrs SCHOOL
24x 40%= 9.6 hrs SLEEPING
24X15%= 3.6 hrs. FREE TIME
ALL ADD UP TO 24 HRS
hope this helps
