5/9 - 1/10 ---> 50/90 - 9/90 = 41/90 ≈ 0,46
2/5 = 4/10 minus 1/10 is 3/10
1 - 1 = 0
9/10 minus 1/10 is 4/5
2/10 which is 1/5
3/2 minus 1/5 = 1 3/10
It is: 4/5 minus 1/2 = 3/10
4/10 - 1/5 = 2/5 - 1/5 = 1/5
3/5 - 1/10 --> 6/10 - 1/10 = 5/10 = 1/2.
1/10 is.
4/5 - 1/10...8/10 - 1/10 = 7/10
1/5 - 1/10 = 2/10 - 1/10 = (2 - 1)/10 = 1/10
3/5
