Tips
  • 6/9 simplifies to 2/3 (divided by GCD of 3).
  • The decimal value helps you understand the fraction's size.
  • Negative fractions are also supported.

What is Fraction Simplifier?

A fraction simplifier is a mathematical tool that reduces a fraction to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD). For example, the fraction 18/24 simplifies to 3/4 because both numbers are divisible by 6. A fraction simplifier is used by students, teachers, engineers, and anyone working with ratios, measurements, or proportional calculations who needs to express fractions in their simplest, most readable form.

How to Use Fraction Simplifier

1
Write down the numerator and denominator of your fraction. For example, 36 over 48.
2
Find the greatest common divisor (GCD) of both numbers. The GCD of 36 and 48 is 12.
3
Divide both the numerator and the denominator by the GCD. 36 divided by 12 equals 3. 48 divided by 12 equals 4.
4
The simplified fraction is 3/4. This is the lowest possible form because 3 and 4 share no common divisors other than 1.
5
To use an online fraction simplifier, enter the numerator and denominator into the tool and click Simplify.
6
The tool displays the simplified fraction, the GCD used, and often the step-by-step working so you can learn how to simplify a fraction as you go

Why Use Fraction Simplifier?

Clarity: Simplified fractions are easier to interpret. 3/4 is immediately recognisable in a way that 36/48 is not.
Calculation accuracy: Using unsimplified fractions in multi-step maths problems increases the risk of arithmetic errors at every stage.
Educational support: An online fraction simplifier shows the working process step by step, helping students understand how to simplify a fraction rather than just giving the answer.
Recipe and ratio scaling: Cooks, chemists, and engineers working with ratios need fractions in their lowest terms for accurate scaling.
Test and exam preparation: Standardised maths exams require answers in simplified form. A fraction simplifier helps students check their work before submission.
Speed: Finding the GCD manually for large numbers is time-consuming. A fraction simplifier handles any size of numerator and denominator in under a second.
