4/10 or 2/5
10/4 - z - 8/16 = 21/2 - z - 1/2 = 2 - z
4/5 - 2/10 = 4/5 - 1/5 = 3/5
1/10 - 1/2 = 1/10 - 5/10 = -4/10 = -2/5
4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
9/10 minus 1/10 is 4/5
10/12 minus 2/4 is 1/3
It is: 4/5 minus 1/2 = 3/10
2/5 = 4/10 minus 1/10 is 3/10
1/4 − 10/11 = -29/44
9/10 − 4/5 = 1/10
4/10 - 1/5 = 2/5 - 1/5 = 1/5
1/4 - 1/10 = 5/20 - 2/20 = 3/20
9/10 - 4/5 = 9/10 - 8/10 = 1/10
4/10 or 2/5
10/4 - z - 8/16 = 21/2 - z - 1/2 = 2 - z
4/5 - 2/10 = 4/5 - 1/5 = 3/5
