A = 1/2 + 1/4 = 2/4 + 1/4 = 3 /4
B = 1 /2 + 5/6 = 3 /6 + 5/6 = 8 /6 = 4 /3
C = 1/2 + 3 /10 = 5/10 + 3 /10 = 8/10 = 4 /5
D = 2/3 + 1 /6 = 4/6 + 1/6 = 5 /6
E = 5/4 + 7/2 = 5/4 + 14/4 = 19 /4
F = 7/12 + 5/3 = 7/12 + 20/12 = 27/12 = 9/4
G = 2 + 1/3 = 6/3 + 1/3 = 7/3
H = 5/3 + 3 = 5/3 + 9/3 = 14/3
I = 4 + 7/5 = 20/5 + 7/5 = 27/5
