Question
How do I simplify a ratio?
Divide both parts of the ratio by their greatest common factor. That reduces the ratio to its simplest whole-number form when possible.
Math
Use OmniCalc's ratio calculator to simplify two values, compare proportions, and find equivalent ratio values in seconds.
Ratio calculator
Enter two values to reduce the ratio, see the proportional share, and calculate an equivalent value that keeps the same relationship.
Why this result matters
A quick ratio and proportion tool for everyday scaling and comparison problems. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This ratio calculator helps with proportion problems without forcing you to do simplification steps manually. It is useful for recipes, layouts, classroom math, pricing, screen proportions, and any situation where two values need to stay in the same relationship.
Formula and method
Ratios compare two quantities in relation to each other. A ratio is simplified by dividing both values by their greatest common factor, and equivalent ratios are found by scaling both sides by the same multiplier.
Example
If a recipe uses 2 parts of one ingredient for every 3 parts of another, or if you need to keep a layout in the same proportion while resizing it, this calculator shows the simplified and equivalent values quickly.

Question
Equivalent ratios keep the same proportional relationship by multiplying or dividing both sides by the same number.
Question
A ratio compares two quantities directly, while a percentage expresses one quantity as a share of 100. They are related, but they answer slightly different questions.
