Enter Ratio Values
Use any two to six values. Decimals are supported.
Example Data Table
These examples show how raw values collapse into their simplest ratio form.
| Example | Entered Values | Scaled Integers | Greatest Common Divisor | Simplest Ratio |
|---|---|---|---|---|
| Basic whole numbers | 12 : 18 : 30 | 12 : 18 : 30 | 6 | 2 : 3 : 5 |
| Decimal ingredients | 1.5 : 2.25 : 3.75 | 150 : 225 : 375 | 75 | 2 : 3 : 5 |
| Four-part split | 20 : 35 : 45 : 50 | 20 : 35 : 45 : 50 | 5 | 4 : 7 : 9 : 10 |
| Zero included | 0 : 2 : 8 | 0 : 2 : 8 | 2 | 0 : 1 : 4 |
Formula Used
The calculator simplifies ratios by converting every value into a comparable integer, then dividing every term by the greatest common divisor.
This keeps decimal ratios exact while preserving the same proportional relationship.

Frequently Asked Questions
1. What does the simplest ratio mean?
It is the smallest whole-number version of a ratio that keeps the same proportion between all terms. Each value is divided by the shared greatest common divisor.
2. Can I simplify decimal ratios?
Yes. The calculator scales every decimal into an integer using a common power of ten first. That lets the reduction stay accurate before the final simplest ratio is shown.
3. How many terms can I enter?
You can enter between two and six values. Blank fields are ignored, so you only need to fill the terms required for your current ratio problem.
4. Does the tool accept zero values?
Yes. Zero can appear inside a ratio, such as 0 : 2 : 8. However, all values cannot be zero because no meaningful proportional reduction exists then.
5. What happens with negative values?
Negative values are allowed. The tool simplifies them normally, then adjusts the sign direction so the first non-zero simplified term displays as positive for easier reading.
6. What is the ratio to the first term?
That comparison expresses every term relative to the first non-zero entry. It helps you see scale differences quickly, especially in mixing, budgeting, and analytical comparisons.
7. What is included in the CSV download?
The CSV file includes the summary values and the detailed result table. You can open it in spreadsheet tools for reporting, checking, or further calculations.
8. What is included in the PDF download?
The PDF export captures the current ratio summary and detailed term breakdown. It is useful for homework, process notes, presentations, and quick document sharing.
