If denomination < the nominator
but what if there are X's and X^2's present in both
5. I'm not sure about C4 (starting that tomorrow) but in C3, wasn't it that the degree of the numerator was equal to or greater than the degree of the denominator?

The degree of something is the power that it's raised too. So, (x - 2) has a lower degree than x^2.

So, then;

(x - 2) over x^2 is not improper, but
x^2 over (x - 2) is improper.

Hope this helps.
8. If the highest degree power (i.e. 4x^2 < x^3) on the numerator is bigger than the highest degree power in the denominator, then it is an improper fraction.

So [(3x^5+4x)/(2x^2)] is an improper fraction. Does that help?
