What have you attempted so far? You can do the first step using:

$$\frac{{\frac{a}{b}}}{{\frac{c}{d}}} = \frac{a}{b} \cdot \frac{d}{c}$$

That is: a fraction of two fractions is the same as the product of the top fraction with the inverse of the bottom fraction.

Give it a shot

Also,

$$\frac{{\frac{a}{c}}}{{\frac{b}{c}}} = \frac{a}{b}$$

(A very useful version of what TD supplied earlier.)

If you remember to make common denominators before combining fractions, and remember how to factor the difference of perfect squares, you should be all set.

The fractions have been posted as "gif"s which can take "forever" to load. Much better to use LaTex.
