Ratio Calculator

How this tool works

A ratio compares two quantities. Simplifying a ratio means dividing both values by their common factor so the relationship is shown with smaller equivalent numbers.

How to use it

1. Enter a non-zero whole number in each field.
2. Select Simplify.
3. Read the reduced ratio and confirm that both values were entered in the intended order.

Example and practical tips

The ratio 12:18 simplifies to 2:3 because both numbers can be divided by 6.

Ratios are meaningful only when the quantities are comparable and their order is correct. This page is intended for non-zero whole-number inputs; use a different method for ratios involving units, decimals or a zero value.

Frequently asked questions

Does simplifying change the relationship?

No. Dividing both parts by the same common factor keeps the ratio equivalent.

Can I enter zero?

The current tool requires both fields to be non-zero for a result.
