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.
?What is the difference between ratio and proportion?
A ratio compares two quantities (A:B), while a proportion states that two ratios are equal (A:B = C:D).

This tool handles two-value ratios (A:B). For three or more values, simplify each pair separately.
