Ratio Simplifier Calculator with Steps
Simplify ratios to lowest terms with detailed step-by-step solutions. Perfect for students, homework, and mathematical simplification. Free calculator with explanations.
Quick Answer
To simplify ratios, find the greatest common divisor (GCD) of numerator and denominator, then divide both by the GCD. This reduces the ratio to its simplest form while maintaining equivalence.

Calculate With Full ToolWhat is Ratio Simplification?
Ratio simplification reduces fractions and ratios to their simplest form by dividing numerator and denominator by their greatest common divisor (GCD). This creates equivalent ratios that are easier to work with and understand.
How Ratio Simplification Works
The process finds the GCD using Euclidean algorithm or prime factorization, then divides both terms by this common factor. The result maintains the same mathematical value but with smaller numbers.
Why Ratio Simplification Matters
Simplified ratios are essential for accurate calculations, clear communication, and advanced mathematics. They're fundamental in algebra, geometry, and problem-solving.
Ratio Simplification Formula
Simplified Ratio = (Numerator ÷ GCD) : (Denominator ÷ GCD)
Greatest Common Divisor: Largest number that divides both numerator and denominator
Simplified Numerator: Original numerator ÷ GCD
Simplified Denominator: Original denominator ÷ GCD
Equivalent Ratio: Simplified numerator : simplified denominator
Step-by-Step Example
Example: Simplifying 24/36
Step 1: Original Ratio: 24/36
Step 2: Find GCD of 24 and 36
Step 3: Prime factors of 24: 2³ × 3
Step 4: Prime factors of 36: 2² × 3²
Step 5: Common factors: 2, 3
Step 6: GCD: 2 × 3 = 6
Step 7: Simplified: (24 ÷ 6) / (36 ÷ 6) = 4/6
Step 8: Further simplify: (4 ÷ 2) / (6 ÷ 2) = 2/3
This example shows how 24/36 simplifies to 2/3 by dividing both terms by their GCD of 6, then further simplifying by dividing by 2. The simplified ratio is equivalent but uses smaller numbers.

Frequently Asked Questions
How do you find the GCD of large numbers?
Use Euclidean algorithm: repeatedly divide larger number by smaller until remainder is 0. The last non-zero remainder is the GCD. For very large numbers, use prime factorization.
Can all ratios be simplified?
Only ratios of integers can be simplified. Ratios with irrational numbers (like π) or decimals cannot be simplified to integer ratios.
What's the difference between simplifying and converting to decimal?
Simplifying keeps the exact fractional form. Converting to decimal gives an approximation that may lose precision. Use simplification for exact mathematical work.
Why are simplified ratios important?
They represent the same value in the most efficient form, making calculations easier and revealing underlying mathematical relationships. Essential for advanced mathematics and problem-solving strategies.
