A ratio is a way to compare two or more numbers to show how much of one thing there is compared with another. It tells you the relationship between amounts.
People use ratios in everyday life to compare things like boys to girls in a class, ingredients in a recipe, or the number of cars to bikes on a road. Ratios help make comparisons clear and easy to understand.
Meaning & Usage
A ratio is often written with a colon, like 2:1, or as a fraction. For example, a 2:1 ratio means there are 2 parts of one thing for every 1 part of another.
Examples
If a class has 10 boys and 15 girls, the ratio of boys to girls is 10:15, which can also be simplified to 2:3. In cooking, a recipe might use a ratio of 2 cups of water to 1 cup of rice.
