-3?
The fraction I got was -87/8

E: I just put it into a mixed number and got -10 7/8.. Still not -3 though.
EE: I got -3.375 when you flip (7/3) perhaps you wrote the problem wrong? The fraction for this is: -27/8

just a quick tip for dividing fractions.

When you have to divide a fraction by a fraction, you can take the numerator from the numerator and multiply it with the denominator from the denominator. Then divide that with denomator from the numerator multiplied by the numerator from the denominator. Idk if that made any sense but ill show it like this.
You have (a/b)/(c/d). This equals to (a*d)/(b*c) so you get rid of the 2 fractions and end up with just 1. Alot easier way to do it :P (ofcourse in your case where there was + or - calcs, those have to be done first to get into a situation where you have 1 fraction divided by another
