1/2 = 5/10 so then 5/10 - 3/10 = 2/10 = 1/5
9/10 - 2/5 = 9/10 * 4/10 = 5/10 = 1/2 or 0.5
4/5 - 2/10 = 4/5 - 1/5 = 3/5
9/10 - 1/2 = 9/10 - 5/10 = 4/10 = 2/5
4/10 or 2/5
2/5 = 4/10 minus 1/10 is 3/10
2/10 which is 1/5
3/5 minus 2/10 is 2/5
It is: 4/5 minus 1/2 = 3/10
3/2 minus 1/5 = 1 3/10
1/2 = 5/10 so then 5/10 - 3/10 = 2/10 = 1/5
9/10 - 2/5 = 9/10 * 4/10 = 5/10 = 1/2 or 0.5
1 − 5/2 = -11/2
4/5 - 2/10 = 4/5 - 1/5 = 3/5
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
9/10 - 1/2 = 9/10 - 5/10 = 4/10 = 2/5
4/10 or 2/5
