### Example Question #1 : How To Divide Complex Fractions

Which of the following is equal to ?      Explanation:

First we must take the numerator of our whole problem. There is a fraction in the numerator with as the denominator. Therefore, we multiply the numerator of our whole problem by , giving us .

Now we look at the denominator of the whole problem, and we see that there is another fraction present with as a denominator. So now, we multiply the denominator by , giving us .

Our fraction should now read . Now, we can factor our denominator, making the fraction .

Finally, we cancel out from the top and the bottom, giving us .

### Example Question #1 : Complex Fractions

Evaluate:       Explanation:

The expression can be rewritten as: Change the division sign to a multiplication sign and take the reciprocal of the second term.  Evaluate. ### Example Question #4 : Complex Fractions

Simplify:       Explanation:

The expression can be simplified as follows:

We can simplify each fraction by multiplying the numerator by the reciprocal of the denominator.  From here we add our two new fractions together and simplify. ### Example Question #1 : How To Divide Complex Fractions

Simplify the following:       Explanation:

Begin by simplifying your numerator. Thus, find the common denominator: Next, combine the fractions in the numerator: Next, remember that to divide fractions, you multiply the numerator by the reciprocal of the denominator: Since nothing needs to be simplified, this is just: ### All ACT Math Resources
