Frequently Asked Questions

?How is a ratio simplified?

Both numbers are divided by their greatest common divisor (GCD). For example, 4:6 becomes 2:3 (divided by 2).

?Can I use decimal numbers?

The tool rounds to the nearest integer before simplifying. For exact decimal ratios, multiply both values to make them whole numbers first.

?What is a ratio used for?

Ratios express the relative size of two quantities, used in cooking, finance, design, engineering, and many other fields.

A ratio compares two quantities (A:B), while a proportion states that two ratios are equal (A:B = C:D).
