About the calculator

The Rationalizing the Denominator Calculator is a handy tool that allows you to simplify fractions with variables by rationalizing their denominators. It is particularly useful when working with radical expressions or fractions containing square roots.

To use the calculator, follow these steps:

  1. Enter the numerator of the fraction in the “Numerator” field.
  2. Enter the denominator of the fraction in the “Denominator” field.
  3. Click the “Calculate” button.

The calculator will then perform the necessary calculation to rationalize the denominator. It achieves this by multiplying the numerator by the square root of the denominator. The result will be displayed in the “Result” section.


Suppose you have a fraction with a numerator of 3 and a denominator of √2. By entering 3 in the numerator field and √2 in the denominator field, the calculator will rationalize the denominator and display the result, which is approximately 4.24.

With the Rationalizing the Denominator Calculator, you can quickly and effortlessly rationalize fractions with variables, making your mathematical calculations more manageable and concise.
