OpenStudy (flower2468):
okay so find then common denominator or the bottom number of 3 and 6,
OpenStudy (anonymous):
You have to find the common denominator of the bottom numbers which is 3 and 6
OpenStudy (anonymous):
so the gcf of 3 and 6
OpenStudy (flower2468):
well, 6 is the common denominator so 6*1=6 and 3*2=6 and you have to do the same thing to the top numbers so 5*1=5 and 2*2=4 so the fractions with common denominators are 5/6 and 4/6, then you need to add them and that equals...?

OpenStudy (flower2468):
well the fraction is an improper fraction so if you 9-6=3 so there is another whle number so you add that to 13 and the fraction is 1/2 so ......14 1/2

1
OpenStudy (flower2468):
which is 6 so 3*2=6 and 2*3=6 and 1*2=2 and 1*3=3 so 2/6+3/6=5/6 and 9+14=23 so 23 5/6 is correct
OpenStudy (anonymous):
but it is not a answer choice
OpenStudy (flower2468):
so what +15=23 5/6
OpenStudy (anonymous):
