A ratio is a way to compare two or more amounts. It shows how much of one thing there is compared with another thing. For example, a ratio of 2:1 means there are 2 of one thing for every 1 of another.
People use ratios in everyday life to compare numbers, mix ingredients, share things fairly, or understand relationships between amounts. You might see ratios in recipes, sports stats, maps, or business reports.
