Why Use an Online Fraction Calculator?

Manually solving fraction problems can be time-consuming and prone to error, especially when dealing with large numerators and denominators or mixed numbers. With this Fraction Calculator, you can:

  • Quickly add, subtract, multiply, or divide mixed numbers.
  • Instantly simplify any fraction to its lowest terms.
  • Convert decimals into clean fractional equivalents and vice versa.
  • Handle very large fractions without complex manual reduction.

This saves time and guarantees accuracy, making it perfect for everything from classroom learning to professional tasks.

Mixed Numbers Calculator Explained

The Mixed Numbers Calculator allows you to perform arithmetic operations on numbers that include both a whole number and a fraction, like 3 1/2 or 7 3/4. Here’s how it works:

  • Convert to improper fractions: A mixed number is transformed into an improper fraction using:
    (Whole × Denominator + Numerator) / Denominator
  • Perform the chosen operation: addition, subtraction, multiplication, or division.
  • Simplify the result: and convert back into a mixed number if applicable.

Example:

Adding 3 1/2 + 2 3/4 becomes 7/2 + 11/4 = 25/4 = 6 1/4.

Simplify Fractions Calculator

This tool is designed to reduce any fraction—small or large—to its simplest form. It divides both the numerator and the denominator by their greatest common divisor (GCD).

Example:

Input: 18/24 → Simplified: 3/4

This is especially useful for recipe adjustments, woodworking measurements, or just keeping math results neat. Even for huge values, like 123456/789012, it instantly finds the simplest equivalent.

Decimal to Fraction Calculator

Want to represent a decimal as a clean fraction? This calculator converts both terminating and repeating decimals into fractional form. It's perfect for turning measurements like 0.375 into 3/8, or financial percentages into exact ratios.

How does it work?

  • For simple decimals: counts decimal places and places over power of 10.
  • For recurring decimals: uses advanced fraction approximation techniques.

Example:

0.75 → 3/4

Fraction to Decimal Calculator

This tool works the other way around. Enter a fraction like 7/8 and instantly get the decimal equivalent 0.875. This is crucial for comparing ratios or when you need values in decimal format for financial or scientific calculations.

Benefits:

  • No manual long division required.
  • Handles complex fractions, including improper ones.

Big Number Fraction Calculator

Dealing with enormous fractions? Our Big Number Fraction Calculator handles very large numerators and denominators—like 987654321/123456789—and reduces them accurately to lowest terms. This is extremely helpful in engineering, statistics, and programming scenarios where big numbers often appear.

Benefits of Using This Complete Fraction Calculator Page

  • All essential fraction tools on one page—no need to switch calculators.
  • Handles everything from small school math to industrial-scale figures.
  • Instant, reliable results you can trust.
  • Mobile-friendly and easy to use anywhere.

Limitations & Tips

While this calculator is highly accurate, always double-check entries—especially when typing complex mixed numbers (use 3 1/2 for three and a half, not 3/2). If you're working with advanced algebra or irrational roots, consider using our scientific calculator instead.
