Answer 2

1/4 + 1/3 = (1*3 + 1*4) / (4*3) = 7/12 1/5 + 1/6 = (1*6 + 1*5) / (5*6) = 11/30 1/3 + 2/5 = (1*5 + 2*3) / (3*5) = 11/15 1/8 + 3/7 = (1*7 + 3*8) / (8*7) = 37/56 3/8 + 2/5 = (3*5 + 2*8) / (8*5) = 31/40 1/4 + 1/2 = (1*2 + 1*4) / (4*2) = 3/4 1/6 + 1/3 = (1*3 + 1*6) / (3*6) = 1/2 1/2 + 5/6 = (1*6 + 5*2) / (2*6) = 11/12 2 1/4 + 1 1/8 = (2*4 + 1*8 + 1*1 + 1*8) / (4*8) = 19/8 5 2/3 + 1 1/6 = (5*3 + 2*1 + 1*6 + 1*1) / (3*6) = 36/6 = 6 1/4 + 1/6 = (1*6 + 1*4) / (4*6) = 5/12 1/6 + 1/15 = (1*15 + 1*6) / (6*15) = 7/30 5/6 + 1/8 = (5*8 + 1*6) / (6*8) = 43/48 3 3/8 + 1 5/12 = (3*8 + 3*1 + 1*12 + 5*1) / (8*12) = 61/24 7 1/6 + 2 5/9 = (7*6 + 1*1 + 2*9 + 5*1) / (6*9) = 127/18
