7 1/4-(2 1/3+3 1/2)=7 1/4-(5 2/6+3/6)=7 1/4-5 5/6=2 3/12-10/12=
=1 12/12+3/12-10/12=1 5/12
7 1/4-2 1/3+3 1/2=8 3/12-4/12+6/12=7 12/12+3/12-4/12+6/12=
=7 17/12=8 5/12

7 i 1/4 - (2 i 1/3 + 3 i 1/2) = 7 i 1/4 - ( 2 i 2/6 + 3 i 3/6) = 7 i 1/4 - 5 i 5/6 = 7 i 3/12 - 5 i 10/12 = 6 i 15/12 - 5 i 10/12 = 1 i 5/12
7 i 1/4 - 2 i 1/3 + 3 i 1/2 = 7 i 3/12 - 2 i 4/12 + 3 i 6/12 = 6 i 15/12 - 2 i 4/12 + 3 i 6/12 = 4 i 11/12 + 3 i 6/12 = 7 i 17/12 = 8 i 5/12
6 i 5/6 - (3 i 1/8 + 1 i 1/2) = 6 i 5/6 - (3 i 1/8 + 1 i 4/8) = 6 i 5/6 - 4 i 5/8 = 6 i 20/24 - 4 i 15/24 = 2 i 5/24
6 i 5/6 - 3 i 1/8 + 1 i 1/2 = 6 i 20/24 - 3 i 3/24 + 1 i 12/24 = 3 i 17/24 + 1 i 12/24 = 4 i 29/24 = 5 i 5/24
