Fraction Simplifier

What is a Fraction Simplifier?

A fraction represents a part of a whole — the numerator (top number) tells how many parts you have, and the denominator (bottom number) tells how many equal parts the whole is divided into. Simplifying a fraction means reducing it to its lowest terms by dividing both numerator and denominator by their Greatest Common Divisor (GCD). For example, 12/16 simplifies to 3/4 because both share a GCD of 4. Simplified fractions are easier to work with in calculations, comparisons, and communication.

How to Use This Calculator

Enter the numerator (top number) and denominator (bottom number) of your fraction. Click Calculate to see the simplified fraction in lowest terms, the GCD that was used to simplify it, the decimal equivalent, and the percentage equivalent. This covers all common uses of fraction simplification in one result.

💡 Pro Tips

• ✓To add fractions, first find the LCM of the denominators — use the CalcSphere LCM calculator for this.
• ✓To compare fractions, convert them to decimals — the fraction with the larger decimal is greater.
• ✓Improper fractions (numerator > denominator) can also be simplified — and converted to mixed numbers.
• ✓In cooking and measurements, simplifying fractions makes recipes and conversions easier to work with.
• ✓Programming and engineering often require exact fractions — always simplify before using fractions in formulas.
