What Is a Ratio?
A ratio is a mathematical way to compare two or more numbers. It shows how much of one value exists relative to another.
Example:
- 12 : 18 means for every 12 units of A, there are 18 units of B.
Ratios can be simplified just like fractions to make them easier to understand.

How to Simplify Ratios (Step-by-Step)
To simplify a ratio manually:
Step 1: Write the ratio
Example: 12 : 18
Step 2: Find the Greatest Common Divisor (GCD)
- GCD of 12 and 18 = 6
Step 3: Divide both numbers by the GCD
- 12 ÷ 6 = 2
- 18 ÷ 6 = 3
Final Answer:
2 : 3
Our calculator performs this instantly—even for decimals.
Ratio Calculator Examples

What Are Equivalent Ratios?
Equivalent ratios represent the same relationship using different numbers.
Example:
- 2 : 3
- 4 : 6
- 6 : 9
All are equal because they maintain the same proportion.
Our calculator automatically generates these for you.

Ratio vs Fraction – What’s the Difference?
Although similar, ratios and fractions are slightly different:
| Ratio | Fraction |
|---|---|
| Compares two quantities | Represents part of a whole |
| Written as 2:3 | Written as 2/3 |
| Can compare different units | Typically same unit |
Frequently Asked Questions (FAQ)
What is the simplest form of a ratio?
The simplest form is when both numbers have no common divisor other than 1.
Can ratios include decimals?
Yes. Our calculator converts decimals into whole-number ratios automatically.
What happens if I enter zero?
Ratios cannot include zero as both values must be non-zero for comparison.
Ratios are a fundamental part of math and everyday problem-solving. With our free Ratio Calculator, you can simplify ratios, generate equivalents, and work with decimals in seconds.
