How to use the Ratio Calculator

The Ratio Calculator simplifies a two-part whole-number ratio by dividing both values by their greatest common divisor. It also displays the first value divided by the second as a decimal.

What this tool is useful for

Simplify ratios for recipes, scale drawings, mixtures, and schoolwork.
Compare two quantities in their smallest whole-number form.
View the ratio as a decimal relationship.

Practical example

The ratio 16:24 has a greatest common divisor of 8, so dividing both sides by 8 produces the simplified ratio 2:3.

Helpful tips

Both sides must be divided by the same non-zero factor.
Keep units consistent before creating a ratio.
A ratio with zero requires careful interpretation and division by zero is undefined.
