Enter a ratio like 18 to 24 and get it reduced to its simplest whole-number form, along with the decimal value. Simplifying a ratio means dividing both sides by their greatest common divisor so the numbers stay in the same proportion but become as small as possible, which makes recipes, maps, scale models, and mixing instructions much easier to read. This tool finds the greatest common divisor exactly and also supports decimal inputs by scaling them to whole numbers first. It shows both the reduced ratio and the single decimal ratio so you can use whichever form you need. Type the two parts and the simplified answer appears instantly. All of the math runs locally in your browser, so nothing you enter is sent to a server and there is no waiting.
