8 1/5+5 1/6-3 1/5 = 8 1/5-3 1/5+5 1/6 = 5+5 1/6 = 10 1/6

8 1/8+1 2/3-3 3/4 = 8 3/24+1 16/24-3 18/24 = 6 1/24

6 1/4-2 5/7+6 3/14 = 6 7/28-2 20/28+6 6/28 = 9 21/28 = 9 3/4

5 2/3+2 1/4-1 3/5 = 5 40/60+2 15/60-1 36/60 = 6 19/60

8 7/10-5 3/4+6 1/5 = 8 28/40-5 30/40+6 8/40 = 9 6/40 = 9 3/20

12 7/15-9 3/4+5 11/12 = 12 28/60-9 30/40+5 55/60 = 8 53/60
