1/2 2/3 is the same as 4/6 Subtract 1/6 gives you 3/6 And 3/6 is the same as 1/2
If you mean 8 and 7/12 subtract 2 and 3/8 then it is 6 and 5/24

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8

An easy way to do this is to manipulate the original number and make sure to "undue" all the manipulations you did. For example: pick any number, add 3, subtract 2, subtract the number you started with, you have 1. Example explained: x + 3 - 2 - x = 1. More complex example: pick any number, multiply by 2, add 4, subtract 2, divide by 2, subtract 2, add 4, subtract the number you started with, you have 3. Explained: (((x * 2) + 4 - 2) / 2) - 2 + 4 - x = (2x + 2) / 2 + 2 = x + 3 - x = 3.

-32915 is what you get when you subtract 825 from 33740.
Subtract their numerators, and put on top of the common denominator. Thus, for example, 5/3 - 3/3 = 2/3. Works for addition, too (add the numerators).
