2 3/5 + 1 3/7 = (2+1)(3/5 + 3/7) = 3(21/35 + 9/35) = 3 30/35 = 3 6/7
hero (hero):

OpenStudy (anonymous):
Can not be a 3 at the front unless it's 3 1/2

so it must be 4 1/7
OpenStudy (anonymous):
orr 3 1/2 :D
hero (hero):
2 3/5 + 1 3/7 = (2+1)(3/5 + 3/7) = 3(21/35 + 15/35) = 3 36/35 = 4 1/35
hero (hero):
