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

j = 42/6 + 43/6 = 85 / 6
