last question, i tried to do this but it didnt work.

Answer 2

it just gave a completely different response

Answer 3

First, change the mixed numbers into improper fractions.
-3 and 1/2 = -7/2
-12 and 1/4 = -49/4

Now, your problem will read (-7/2) - (-49/4)
You can change it to this: (-7/2) + (49/4)

Next, you need to make a common denominator.
Multiply the top and bottom of (-7/2) by 2.
This will equal (-14/4).

Now your problem says (-14/4) + (49/4)
-14 + 49 = 35
35/4 = 8.75 or 8 and 3/4

...didn't read the rest of what you said until just now, lol.
What do you mean it didn't work?
