2.8/10 - 1/5 - 1/2 = 8/10 - 2/10 - 5/10 = 1/10

3.11/12 - 2/6 - 1/2 = 11/12 - 4/12 - 6/12 = 1/12

4.16/18 - 3/6 - 1/3 = 16/18 - 9/18 - 6/18 = 1/18

5.13/16 - 4/8 - 1/4 = 13/16 - 8/16 - 4/16 = 1/16

1). 8/12 -1/4 - 1/6 = 8/12 - 3/12 - 2/12 = 3/12 = 1/4
2). 8/10 - 1/5 - 1/2 = 8/10 - 2/10 - 5/10 = 1/10
3). 11/12 - 2/6 - 1/2 = 11/12 - 4/6 - 6/12 = 1/12
4). 16/18 - 3/6 - 1/3 = 16/18 - 9/18 - 6/18 = 1/18
5). 13/16 - 4/8 - 1/4 = 13/16 - 8/16 - 4/16 = 1/16
