🛠️ What is a Ratio Calculator?
The Ratio Calculator by CalculatorSolutions.net is a free and easy-to-use tool that helps you simplify ratios, making them easier to understand and apply. Whether you’re working on a math problem, resizing a recipe, analyzing data, or comparing quantities in business, this calculator helps you reduce any ratio to its lowest terms instantly.
Instead of simplifying manually, let this tool handle it for you with 100% accuracy. Simply enter two numbers, and the calculator will return the simplified ratio in clean format (like 2:3 or 5:8).
✅ How to Use the Ratio Calculator
Using the calculator is simple:
- Enter the first value (e.g., 20)
- Enter the second value (e.g., 30)
- Click “Simplify Ratio”
- The tool will automatically reduce the ratio to the lowest whole-number form
It works for any two positive numbers, including decimals and large values, and provides the output in the standard “a : b” format.
📐 How the Formula Works
To simplify any ratio (like 20:30) into its smallest whole-number form, we use a method based on the Greatest Common Divisor (GCD).
✏️ Step-by-step:
- Find the GCD of both numbers.
For example, the GCD of 20 and 30 is 10. - Divide both values by the GCD:
- 20 ÷ 10 = 2
- 30 ÷ 10 = 3
- Resulting simplified ratio = 2 : 3
So, 20:30 simplifies to 2:3.
🧮 Example
Let’s say you’re scaling down a recipe or comparing measurements:
- Input: 20 and 30
- GCD of 20 and 30 = 10
- Simplified: 20 ÷ 10 : 30 ÷ 10 = 2 : 3
✅ Result:
“Simplified Ratio: 2 : 3”
This means the two values maintain a 2-to-3 relationship.
📦 Why Use This Tool?
- ✅ Avoid manual GCD math
- ✅ Quickly convert any ratio into the simplest form
- ✅ Use for recipes, budgets, ingredient scaling, mix proportions, or math homework
- ✅ Works on desktop, tablet, and mobile
- ✅ Completely free and ad-friendly
