95/9 - 6 5/6 simplify if necessary im in fifth grade so i dont do negative numerals yet.

It is not as tough a problem as it seems to you. You can easily grasp the problem, once it is done,

9 5/9 - 6 5/6 = 86/9 - 41/6
                    = (172 - 123)/18
                    = 49/18
                    = 2 13/18

I hope that the simplification process is simple enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
