ingab2989 · Answer

1-5/9 = 9/9 - 5/9 = 4/9
10-5/9 = 90/9 - 5/9 = 85/9 = 9 4/9
2 4/9-1 5/9 = 22/9 - 14/9 = 8/9
1-2/5 = 5/5 - 2/5 = 3/5 = 0,6
12-2/5 = 60/5 - 2/5 = 58/5 = 11,6
3 2/5-2 3/5 = 17/5 - 13/5 = 4/5 = 0,8
1-12/13 = 13/13 - 12/13 = 1/13
11-12/13 = 143/13 - 12/13 = 131/13 = 10 1/13
10 1/3-9 2/3 = 31/3 - 29/3 = 2/3
