he spent 135 minutes on homework
there are (60min/hr)(24hr/day)=1440 minutes in a day
So 135/1440= 9.375% of the day spent on homework

The first answer was correct.
2 hours and 15 minutes is 2.25 hours (2.25 since 15 minutes is a quarter of an hour)
2.25/24 = .09375 = 9.375%
Though a more interesting question would be what percent of waking hours did he spend on homework....
Assuming that he sleeps 8 hours a night, we would do: 2.25/16 and get 14.0625%... poor guy needs to have some fun.

OK.
2 hr 15 min =135 minutes in total
24hr * 60 minutes = 1440
Divide 1440/135= 0.09375 * 100
The estimate should be 9.375% which is almost 9.4%

9.375%
(0.09375 * 100) = 9.375 (the answer above from BHAJUN is a typo, but his initial answer was right)
You can also take the total number of minutes in the day (1440) and divide it into the number of minutes spent on homework (135) -- 135 divided by 1440 = 0.09375 or 9.375%
Speaking of homework - do your own next time ;)

24 hours in a day, 2.25 hours on homework,
2.25 hours/24 hours = %/100
(2.25)(100) = 24x
x=225/24 = 9.375% of the day spent on HW

2hrs 15 min = 135min
24 *60 = 1440 min
135/1440*100 = 9.375%

2 hours and 15 minutes is 2.25 hours
There are 24 hours in a day...I'm assuming you mean an entire day, including the time he sleeps. To find a percentage, divide the time he spent by the total number of hours in a day, and multiply by 100
[2.25 / 24] * 100%
0.9375 * 100%
9.735%
So bout 9.7% of his day was spent on homework

24 hours in a day, spending 2.25 hours on homework. Divide 2.25 into 24 will give you your answer.

9.4%
2.25 hrs / 24 hrs = .09375
There You Go! Just Make It Into A Sentence.

divide 2.25 by 24 and move the decimal to the right 2 spaces. i'm too lazy to do this myself!
the above answer is way off- 2 hours and 15 min. is nowhere near 94% of 24!!!!!!!!!!!!!!!!!!!!!!!
