For example:

It works the same way with variables:

You have to be careful when dividing fractions that have polynomials for the numerator and denominator:

Now using FOIL we can simplify the expression further:

Now for the problem in the practice test it is easier to first factor the individual fractions:

Now simplify:

Now flip the fraction and multiply:
