Answer 1

1/4-1/8+5/6 = 6/24-3/24+20/24 = 23/24
2/7+1/2-10/28= 8/28+ 14/28-10/28 = 12/28 = 3/7
2 i 2/3-1i 9/12 + 3 i 10/15= 8/3 - 21/12 + 55/15 =
8/3 - 7/3 + 11/3 = 12/3 = 4
5 i 1/2-2 i 2/3+3 i 3/8= 132/24 - 64/24 + 84/24 = 152/24 = 19/3 = 6i1/3

Answer 2

1/4-1/8+5/6=6/24-3/24+20/24=23/24
2/7+1/2-10/28=8/28+14/28-10/28=12/28
2 i 2/3-1i 9/12 + 3 i 10/15=2 40/60-1 45/60+40/60=1 35/60
5 i 1/2-2 i 2/3+3 i 3/8=5 12/24-2 16/24+3 9/24=6 5/24
17/4-2 i 1/10+42/40=4 1/4-2 1/10+1 2/40=4 10/40-2 4/40+1 2/40=
