You asked about "to the minus" so we will talk about integers to the minus. Such as 2 to the minus 2. This means 1 over 2 to the positive two. In general a to the minus b is 1/a to the b
6/14 minus 2/7 = 3/7 - 2/7 = 1/7
1/2 minus 3/7 is 1/14
3/6, or 1/2
2 − 1/6 = 15/6
3/2 minus 1/5 = 1 3/10
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
It is: 4/5 minus 1/2 = 3/10
1 over 2
If you mean: 7/1-2/5-5 then the answer is 8/5 or 1.6
1 and 1 over 3
Seven minus four and a half is two and a half.
