Look if there are still factorable expressions in your answer. See if there are any thing that you can cancel. If there is nothing that you can remove or cancel, your answer in the simplest form. For example: Your answer is (4/48). See that 4 and 48 has a common factor of 4. Divide each with four (4/4) / (48/4). You will get the answer of (1/12). That is the simplest form.
