Fraction Calculator

Add, subtract, multiply, divide, and simplify fractions instantly with this free step-by-step online fraction calculator tool.

A fraction represents a part of a whole, written as a numerator over a denominator. To add or subtract fractions, convert them to a common denominator first; to multiply, multiply numerators and denominators directly. For example, 1/4 + 1/6 becomes 3/12 + 2/12 = 5/12, and 2/3 × 3/5 = 6/15, which simplifies to 2/5.

How to Simplify Fractions in 3 Easy Steps

Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1. Here's how you do it:

Step 1: Find the Greatest Common Factor (GCF) of the numerator and denominator. The GCF is the largest number that divides evenly into both numbers.
Step 2: Divide both the numerator and denominator by the GCF.
Step 3: Write the simplified fraction.

Example: Simplify 6/8

GCF of 6 and 8 is 2
6 ÷ 2 = 3, 8 ÷ 2 = 4
Answer: 3/4

See how easy that is? Our simplify fractions calculator follows these exact steps, but it does all the work in milliseconds! If you need to convert fractions to decimals, you can also try our Fraction to Decimal Calculator.

Simplify Improper Fractions to Mixed Numbers

An improper fraction is any fraction where the numerator (top number) is greater than the denominator (bottom number), such as 16/3, 81/9, or 525/71.

When you simplify an improper fraction, you convert it to a mixed number: a whole number plus a proper fraction.

Our simplify improper fractions tool handles this conversion automatically. Here's how it works:

Example 1: Simplify 16/3

Step 1: Divide 16 by 3 → 16 ÷ 3 = 5 with remainder 1.
Step 2: The whole number is 5.
Step 3: The remainder (1) becomes the new numerator.
Step 4: The denominator stays 3.
Answer: 5 1/3

Example 2: Simplify 45/10

Step 1: Find the GCF of 45 and 10 → GCF is 5.
Step 2: Divide both by 5 → 45 ÷ 5 = 9, 10 ÷ 5 = 2 → 9/2.
Step 3: Divide 9 by 2 → 9 ÷ 2 = 4 with remainder 1.
Answer: 4 1/2

Using a simplify improper fractions calculator makes this process instant and error-free. To convert mixed numbers or improper fractions, you can also use our specialized Mixed Number Fraction Calculator.

Simplify Mixed Fractions: Quick Method

A mixed fraction combines a whole number and a proper fraction, like 4 1/2 or 2 3/4. When you need to simplify mixed fractions, you follow this process:

Step 1: Convert the mixed number to an improper fraction: Multiply the whole number by the denominator, add the numerator, and keep the same denominator.
Step 2: Simplify the improper fraction using the GCF method.
Step 3: Convert back to a mixed number (if needed).

Example: Simplify 2 4/8

Step 1: 2 × 8 = 16, 16 + 4 = 20 → 20/8
Step 2: GCF of 20 and 8 is 4 → 20 ÷ 4 = 5, 8 ÷ 4 = 2 → 5/2
Step 3: 5 ÷ 2 = 2 with remainder 1
Answer: 2 1/2

Our simplify mixed fractions calculator does all this work for you, instantly!

Advanced: Simplifying Exponents Fractions

When you're working with algebra, you might encounter fractions with exponents, like (x²/y²) or (2/3)². Simplifying exponents fractions follows a simple rule:

Basic Rule: (a/b)^n = a^n / b^n

This means you apply the exponent to both the numerator and the denominator.

Example 1: (2/3)² → Numerator: 2² = 4, Denominator: 3² = 9 → Answer: 4/9
Example 2: (x/y)³ → Numerator: x³, Denominator: y³ → Answer: x³/y³
Example 3: (3x/4y)² → Numerator: (3x)² = 9x², Denominator: (4y)² = 16y² → Answer: 9x²/16y²

Our simplifying exponents fractions tool handles these automatically, but understanding the rule helps you check your work.

Real-Life Applications: When Will You Use This?

You might be wondering: "When will I ever need to simplify fractions in real life?" The answer: more often than you think!

1. Cooking and Baking: You're following a recipe that calls for 3/4 cup of flour, but you only have a 1/2 cup measuring cup. Simplifying fractions helps you figure out equivalent proportions.

2. Splitting Bills: You and your friends are splitting a $30 bill 5 ways. That's 30/5 = 6/1 → each person pays $6.

3. Measurements: You're working on a DIY project and your measurement is 12/16 inch. Simplified, that's 3/4 inch, much easier to read on your tape measure!

4. Shopping Discounts: A store offers a "buy 2 get 1 free" deal. That means 2/3 of the items are paid for.

Our simplify fractions calculator helps you with all these scenarios and more!

Step-by-Step Visual Example

Let's work through a complete simplifying fraction problem together. This visual guide shows you exactly what happens.

Problem: Simplify 24/36

Step 1: Find the GCF of 24 and 36.

* Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

* Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

* Common factors: 1, 2, 3, 4, 6, 12 → GCF = 12

Step 2: Divide numerator by GCF: 24 ÷ 12 = 2.
Step 3: Divide denominator by GCF: 36 ÷ 12 = 3.
Step 4: Write simplified fraction → Answer: 2/3

*(Check your work: 2/3 × 12/12 = 24/36)*
