# What is 10/21 Simplified?

Are you looking to calculate how to simplify the fraction 10/21? In this really simple guide, we'll teach you exactly how to simplify 10/21 and convert it to the lowest form (this is sometimes calling reducing a fraction to the lowest terms).

To start with, the number above the line (10) in a fraction is called a numerator and the number below the line (21) is called the denominator.

So what we want to do here is to simplify the numerator and denominator in 10/21 to their lowest possible values, while keeping the actual fraction the same.

To do this, we use something called the greatest common factor. It's also known as the greatest common divisor and put simply, it's the highest number that divides exactly into two or more numbers.

In our case with 10/21, the greatest common factor is 1. Once we have this, we can divide both the numerator and the denominator by it, and voila, the fraction is simplified:

10/1 = 10

21/1 = 21

10 / 21

As you can see, 10/21 cannot be simplified any further, so the result is the same as we started with. Not very exciting, I know, but hopefully you have at least learned why it cannot be simplified any further!

So there you have it! You now know exactly how to simplify 10/21 to its lowest terms. Hopefully you understood the process and can use the same techniques to simplify other fractions on your own. The complete answer is below:
