About Fractions

What Are Fractions?

Fractions represent parts of a whole. They consist of a numerator (top number) and a denominator (bottom number), separated by a fraction bar.

Example: 3/4 means 3 parts out of 4 equal parts.

Fractions are fundamental in mathematics, used in measurements, ratios, probabilities, and many real-world applications like cooking, construction, and finance.

How Our Calculator Works

Our advanced fraction calculator performs operations following precise mathematical rules:

  • Addition/Subtraction: Finds common denominator, then adds/subtracts numerators
  • Multiplication: Multiplies numerators and denominators directly
  • Division: Multiplies by the reciprocal of the second fraction

The calculator automatically simplifies results to their lowest terms using the greatest common divisor (GCD).

How To Use This Tool

  1. Enter numerators and denominators for both fractions
  2. Select the operation you want to perform
  3. Click "Calculate" or press Enter
  4. View your result as a simplified fraction and decimal equivalent

Pro Tip: You can click the operation buttons to quickly change operations without reselecting from the dropdown.

Practical Applications

Fraction calculations are essential in many fields:

  • Cooking: Adjusting recipe quantities and measurements
  • Construction: Precise measurements of materials
  • Finance: Calculating interest rates and proportions
  • Education: Fundamental math concepts and problem solving
  • Science: Data analysis, measurements, and ratios
  • Everyday Life: Comparing prices, measuring ingredients, time management
