Jereen spent 1/4 hour on homework after school, another 1/2 hour after she got home, and final 1/3 hour after dinner. Did she spend more or less than 1 hour on homework in all?



Answer :

more than 1 hour.
1/4 + 1/2 is the same as 1/4 + 2/4 = 3/4
3/4 + 1/3 is the same as 9/12 + 4/12 = 13/12
13/12 = 1 1/12
More than an hour. Spent 1 hour 5 mins on homework...
1/4 hour = 15 mins
1/2 hour = 30 mins
1/3 hour = 20 mins
