4/5 - 1/10...8/10 - 1/10 = 7/10
1/2 = 5/10 so then 5/10 - 3/10 = 2/10 = 1/5
2/5 − 1/10 = 15/50 which reduces to 3/10
1/10 - 1/2 = 1/10 - 5/10 = -4/10 = -2/5
1/10
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
3/5 - 1/10 --> 6/10 - 1/10 = 5/10 = 1/2.
4/10 - 1/5 = 2/5 - 1/5 = 1/5
4/5 - 1/10...8/10 - 1/10 = 7/10
1/5 - 1/10 = 2/10 - 1/10 = (2 - 1)/10 = 1/10
1/10 is.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
