Hw help

Well it makes it easier that you have matching denominators. 

You would form the answer like this:

  8                 55

- ---        -     ----

  66               66

Now all you have to do is minus those, but since they are both negative, it would kinda be like adding.

      63

-    -----

       66

Then simplify, you can divide it by 3

      21

-    -----

       22

Hope that helped

Remember the negative

Answer asap plz
