Ratio: A comparison of two quantities expressed as a quotient or using a colon.
Explanation
A ratio shows the relationship between two quantities. Ratios can be expressed as fractions, with a colon, or with the word to. Ratios should be simplified to lowest terms. Equivalent ratios represent the same relationship. Ratios are used in recipes, maps, and many real-world applications. Scaling involves using ratios to enlarge or reduce quantities proportionally.
Example
If a recipe needs 2 cups of flour and 1 cup of sugar, the ratio of flour to sugar is 2:1 or 2/1.
