## How to Simplify a Fraction (Plus an Example)

A simple fraction (or vulgar fraction) is a fraction expressed as an integer over another integer – for example, 1/3, 2/5, and 3/9.

But as you can see, sometimes simple fractions are equivalent. In this case, both 1/3 and 3/9 are the same number – roughly 33.333%. These are known as *equivalent fractions*.

For fractions that can be reduced further – while still staying in the simple fraction form – you take the greatest common factor of both. If they both share a non-1 factor, you can divide the numerator and denominator to find a smaller fraction.

Let's look at 3/9's prime factorization and list out all primes:

As you can see, both numerator and denominator can be divided by 3. Now, let's reduce 3/9:

And now as you can see, 1/3 and 3/9 are equivalent fractions.

## How to Use the Fraction Simplifier

To simplify a fraction, simply enter the **numerator/top number** (on the left side) and the **denominator/lower number** (on the right side) of the input but. Then, hit the Simply Fraction button and we'll reduce it to the most basic simple fraction.
