How to convert a fraction to a percentage

Change from fraction to percentage

Transform a fraction into a percentage is as simple as apply the following formula:

% = (numerator/denominator) x 100

In other words, we have to divide the numerator of the fraction by its denominator, then multiply by 100 to obtain the result in percentage format.

For example, if you want to know the percentage of 1/2, you have to:

% = (1/2) x 100 = 50%

Convert a fraction to a percentage in Excel

If our fraction to percentage converter is useful for you but you want to create a calculator in Excel to make the change without needing internet, here are the steps to follow.

Just open a spreadsheet and select two empty cells:

  • La primera de ellas la usaremos para escribir la fracción por lo que tienes que cambiar su formato de celda a la categoría de "Fracción".
  • En la segunda celda obtendremos el resultado de pasar la fracción a porcentaje. Para ello, cambiaremos el formato de celda a "Porcentaje" y escribiremos una fórmula para hacer la conversión automáticamente. Por ejemplo, si la fracción la hemos escrito en la celda B2, la fórmula que escribiremos será:


If you have done well, Excel will express the fraction you have written at coordinates B2 (or whatever you have used) as a percentage.

The process is simple but if you have any questions, we recommend you watch the video above or leave us a comment and we will help you as soon as possible.
