28x+14 14x+7

-------- / -------

45x-30 30x-20

Okay, I know the second fraction I need to reverse it and cancel out what I can.

28x+14 30x-20

-------- . --------

45x-30 14x+7

2+2 2-2

----- . -----

3-3 1+1

And now i'm stuck... I'm trying to figure out if I take the sum of 2+2 and multiply it by the remainder of 2-2 and the same thing with the denominator.
