1/6-1/14 = 7/42-3/42=4/42=2/21

1 1/3-5/6 = 4/3-5/6 = 8/6-5/6=3/6 = 1/2

2/3+5/6 = 4/6+5/6 = 9/6=3/2 = 1 1/2

5/6+7/10 = 25/30+21/30=46/30=23/15 = 1 8/15

2 1/3+1/6 = 7/3+1/6 = 14/6+1/6 = 15/6 = 5/2 = 2 1/2

2 1/2+3/10 = 5/2+3/10 = 25/10+3/10 = 28/10=14/5 = 2 4/5

6 - 3 4/5 = 6-19/5 = 30/5-19/5 = 11/5=2 1/5

4 3/4-2 1/8 = 19/4-17/8 = 38/8-17/8=21/8 = 2 5/8

5 4/15-2 1/10 = 79/15-21/10=158/30-63/30 = 95/30 = 19/6 = 3 1/6
