Are You Ready to Learn How to Simplify Fractions?

Learning how to simplify fractions is an important concept in math." When working with fractions, most directions will require that you submit your answer in lowest terms. This means that you must simplify your fraction to the point where 1 is GCF for both the numerator and the denominator.

Note: this term also used to be expressed as "reducing" fractions. So, if you are asked to reduce fractions, it means to simplify fractions, which is what we will focus on in this lesson.

In order to fully understand this lesson, you will need to understand greatest common factor (gcf) and possibly prime factorization (or factor trees).

Let's take a look at Example 1.


Example 1

simplify fractions

Sometimes you may try to identify the GCF mentally, and although you may find a common factor, it may not be the greatest common factor. That's ok....

You can still continue to simplify the fraction even if you didn't identify the GCF correctly the first time. Take a look....


Example 2

simplifying fractions

simplifying fractions in one step

As you can see, you can simplify your fractions in more than one step in order to arrive at the lowest term or you can use prime factorization to find the GCF and simplify in one step. Either way will get you to your final answer!

Going back to equivalent fractions, you can determine if two or more fractions are equivalent by simplifying all to lowest terms. If two fractions or more fractions are equivalent, then they will all be simplified to the same fraction. Let's take a look at this last example.


Example 3

equivalent fractions

As you can see, it's pretty easy to simplify fractions. Identify the GCF and divide both the numerator and denominator by the GCF. This will state your answer in simplest form.

You are now ready to move onto the next fractions lesson which is finding the least common multiple.

What People Are Saying...


"I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out.

It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"

Jimmy - United States



"I stumbled onto your site after I found out that I needed to use some fundamental algebra for an assignment. Turns out I had forgotten some things and your great site helped me remember them like "that" (snap of fingers). The organization of the site let me find exactly what I was looking for so easily. Kudos to you for maintaining such a great resource for students of all ages!"

Tom - United States



"I just wanted to write and basically thank you for making such a wonderful website! I'm 20 years old and about to take a basic placement test for college. I wanted to brush up on my Algebra skills and I stumbled upon your site. I'm amazed at how simple you make it and how fast I'm remembering Algebra! I don't remember getting most of the answers right when I had an actual teacher in front of me teaching this. Thanks a lot!"

Elizabeth - United States



"I am a pensioner living in South Africa. I stumbled on your website, the best thing that could ever happen to me! Your course in Algebra has helped me a lot to better understand the different concepts. Thank you very much for sharing your skills for teaching math to even people like me. Please do not stop, as I am sure that your teachings have helped thousands of people like me all over the world."

Noel - South Africa



This is an amazing program. In one weekend I used it to teach my Grade 9 daughter most of the introductory topics in Linear Relations. I took her up to Rate of Change and now she can do her homework by herself.
