3/5 - 1/10 --> 6/10 - 1/10 = 5/10 = 1/2.
4/10 - 1/5 = 2/5 - 1/5 = 1/5
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
1 − 5/2 = -11/2
2/5 - 3/10 = (2×2)/(5×2) - 3/10 = 4/10 - 3/10 = (4-3)/10 = 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
1/10 is.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
3/5
