Learn How to Multiply Fractions

Are you ready to learn how to multiply fractions? Multiplying fractions is one of the easier operations when working with fractions.

Yes, it's true! There's no worrying about finding a common denominator, you just have to know your multiplication facts!

Now, you will need to know how to simplify fractions, but we'll get to that in a minute.

Multiplying Fractions in 3 Easy Steps

  • Step 1: Multiply the numerators.
  • Step 2: Multiply the denominators.
  • Step 3: Simplify the fraction if needed.
  • Let's check it out.

    Example 1

    In this example, we will multiply two very simple proper fractions and apply the 3 steps above.

    This method works pretty well if the numerator and denominators of your fractions are relatively small. When you start working with larger numbers in the numerator and denominator, then we can simplify within the problem before multiplying and this allow us to not have simplify larger numbers in the end. Here's what I mean, take a look....

    Example 2

    There are two problems for Example 2. The first problem, we will multiply the fractions following the steps above. In the second problem (which is exactly the same), we will simplify within the problem first, and then multiply.

    Now, let's take a look at the same problem, but we will simplify first.

    Now let's take a look at one more example where the numerator and denominator that have a common factor are not contained in the same fraction. Remember, the process is the same!

    Example 3

    Pay careful attention to the first and second steps when multiplying this set of fractions.

    Since simplifying within the problem can be a little more confusing, take a look at this example on the video for a step-by-step explanation.

    I hope this helps your understanding of how to multiply fractions. Don't forget to work smarter and not harder - simplify first, then multiply!

    What People Are Saying...

    Dear Karin,

    I am a homeschool mom of five who struggled with finding a solid algebra program for my older boys until I came upon your algebra class. Your tutorials are straight forward and detailed. Your assignments are designed in such a way that we can spend extra time on what my children need to and move on when they understand something more easily.

    I am a math-lover myself and am excited that you have finished part 2 of this course. My boys are understanding algebra in a way that they never were able to with other courses due to the detail and care that are in each of your lessons. I also appreciate that you are available to answer questions.

    Thank you,

    Jacqui Coleman

    Dear Karin,

    Finding your site was such a blessing to me! I have been out of school for 13+ years and finding out that my next course would be Algebra scared me to death!

    I have now found a new love of learning for algebra--something I never thought would happen. After indulging in the section of functions, I decided to explore other areas that I have just learned. It made areas such as inequalities and graphing so much easier to grasp!

    I just wanted to thank you for your passion and dedication for helping others! I also love the fact that you add in some humor, too. I have shared your site with classmates and hope they take an opportunity to look into it as well! Thank you----

    With greatest respect,


    Hi Karin,

    I just spent 3 hours doing Unit 5 Lessons 1 & 2 because that is what I am learning at school this week, and cannot believe my progress. I so wish I would have found your course sooner. It is amazing. You explain everything in such clarity it's like night and day. Thank you so much for getting me started. I am so happy you can't believe it. You are the best instructor ever!

    Thanks again.
