Provide two numbers to simplify and compare ratios.

How Ratio Calculation Works

A ratio compares two quantities. Simplifying a ratio means dividing both numbers by their greatest common divisor (GCD).

Formula

Simplified Ratio = (A ÷ GCD) : (B ÷ GCD)

Percentage Conversion

Percentage = (A ÷ B) × 100

Example

If you enter 20 and 50:

  • GCD = 10
  • Simplified Ratio = 2 : 5
  • Percentage = 40%
  • Equivalent Ratio (×10) = 20 : 50
