OpenStudy (katherinkoon):
you can explain how or just give me the answer
OpenStudy (moldybubblegum11):
so its 22 11/15
OpenStudy (moldybubblegum11):
to figure this out you need a common denominator, to get that you need to make the 3 a 15
OpenStudy (moldybubblegum11):

than it would be 7 2/15 + 5 10/15 + 9 13/15
OpenStudy (moldybubblegum11):
the best way to solve this is by adding the whole numbers first. so add 7, 5 and 9. that equals 21
OpenStudy (moldybubblegum11):
next you have to add the fractions. once you add them up the answer will be 21 25/15

to do that subtract 25 by 15. the answer is 10
