9/14 + 2/14 = 11/14
11 5/6 + 2 4/6 = 13 9/6 = 14 3/6 = 14 1/2
1 1/3 - 2/3 = 4/3 - 2/3 = 2/3
5 1/4 - 2 2/4 = 4 5/4 - 2 2/4 = 2 3/4
108 2/5 - 7 3/5 = 107 7/5 - 7 3/5 = 100 4/5
3/5 + 1/4 = 12/20 + 5/20 = 17/20
6/7 - 2/21 = 18/21 - 2/21 = 16/21
4 1/12 - 1/6 = 4 1/12 - 2/12 = 3 13/12 - 2/12 = 3 11/12
7 1/8 - 2 2/3 = 7 3/24 - 2 16/24 = 6 27/24 - 2 16/24 = 6 11/24
11 1/3 - 5 4/9 = 11 3/9 - 5 4/9 = 10 12/9 - 5 4/9 = 5 8/9
