Calculation simplification fraction

Simplify a fraction

Enter a numerator and a denominator to find the most simplified equivalent fraction.


Equivalent factors

Several factors are equal in their values.

Let us take for example, a pizza cut into 6 equal parts and where I decide to take 2 slices , the fraction is therefore 2 / 6 .

If I had decided to cut my pizza into 3 equal slices , to obtain the same quantity of pizza, I would have had to take 1 single slice for a fraction of 1/3

In order to obtain a more complete list of equivalent fractions, we must therefore multiply the numerator and the denominator by the same number.

Here are some factors equal to or equal to 1/3:

13 = 26 = 39 = 412 = 515 = 618 = etc...

Formula for simplification

By common fractors

In order to obtain the most simplified equivalent fraction, we must first find the greatest common and integer factor of the numerator and the denominator.

Take for example the fraction 8/40

The numerator 8 has the following factors: 1, 2, 4, 8

The denominator 40 has the following factors: 1, 2, 4, 5, 8, 10, 20, 40

So you notice that the greatest common factor is 8.

So now we have to divide our numbers by 8 like this:

8/840/8 = 15
