Best ResponseYou've already chosen the best response.0http://www.wolframalpha.com/input/?i=%2825%29%2F%286%2F5%29 Depending how you put it into Wolfram you could get 5/6, though I'm not 100% sure why..

Best ResponseYou've already chosen the best response.13/8 + 5/7 (7/7)*(3/8) +5/7 21/56 +5/7 21/56 + (5/7)*(8/8) 21/56 + 40/56 (21+40)/56 61/56 So 3/8 + 5/7 = 61/56
