Multiplying Fractions

Multiplying fractions is not NEARLY as hard as adding or subtracting them! In fact, if you know your times tables, you will be fine. In order to multiply fractions, you do NOT need common denominators! You simply set up the multiplication problem, like this:

Then you multiply straight across, so the numerators get multiplied together, and the denominators get multiplied together. In this case, you would be multiplying 1 x 1 (the numerators) and 2 x 4 (the denominators). When complete, it will look like this:

Once you get your answer, make sure it is reduced (if you can reduce it, do so; if not, leave it the way it is). Then, you’re done!

Let's try another one:

Remember, multiply straight across; the numerators get multiplied and the denominators get multiplied.

3 x 2 = 6 (numerators), 4 x 5 = 20 (denominators).

Your complete problem would look like this:

Now, check your answer. Can you reduce it? Yes, you can! Here’s what the reducing would look like:

Your final answer for this problem is 3/10.
