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

-32915 is what you get when you subtract 825 from 33740.
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.
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).
