9 and a half because ten over 1 is 10 and 4 over 8 is a half so 10-0.5=9.5.
It is: 1/2 minus 2/5 = 1/10
1 minus a half is a half.
5 over 8
5 and 8/10 minus 3 and 1/2 = 2 and 3/10
1/2 − 1/10 = 2/5
9 and a half because ten over 1 is 10 and 4 over 8 is a half so 10-0.5=9.5.
1 and 3 over 10
9/10 minus 1/10 is 4/5
2/5 = 4/10 minus 1/10 is 3/10
It is: 1/2 minus 2/5 = 1/10
1/2 minus 1/5 = 3/10
1 minus a half is a half.
4/5 minus 1/2 is the same as 8/10 minus 5/10 = 3/10
1 - 1 = 0
15.
101/2 - 84/5 = 10.5 - 8.8 = 1.7 = 17/10
