A  =  7/3 - 1/3 = 6/3 = 2

B = 7/4 - 9/20 = 35/20 - 9/20 = 26/20 = 13/10

C = 13/11 +  ( - 8/11 x - 3/4) 
    = 13/11 + 24/44
    = 52/44 + 24/44 = 76/44 = 19/11 

D =  7/3  - 30/42 = 98/42 - 30/42 = 68/42 = 34/21

E = 10/3 *  18/15 = 180/ 45 =

F = 6/5 - ( 3/36) = 6/5 - 1/12 =  72/60 - 5/60 = 67/60
