Answer 2

2 2/3 - 1 4/5 = 2 10/15 - 1 12/15 = 13/15
1 2/6 - 2/3 = 8/6 - 4/6 = 4/6 = 2/3
2 1/4 - 1 6/8 = 1 10/8 - 1 6/8 = 4/8 = 1/2 
3 1/3 - 2 10/1 5 = 3 5/15 - 2 10/15 = 2 20/15 - 2 10/15 = 10/15 = 2/3   
2 7/9 -1 1/6 = 2 14/18 - 1 3/18 = 1 11/18
3 4/15 - 1 11/30 = 3 8/30 - 1 11/30 = 2 38/30 - 1 11/30 = 1 27/30
2 7/30 - 1 17/20 = 2  14/60 - 1 51/60 = 1 74/60 - 1 51/60 = 23/60
4 1/100 - 2 3/50 = 3 101/100 - 2 6/100 = 1 95/100 = 1 29/20
