Ratio refers to the quantitative relationship between two or more quantities or variables, typically expressed as a proportion or fraction. It is often used to compare the size or amount of one quantity to another.
For example, a recipe may call for a ratio of 2 cups of flour to 1 cup of sugar, meaning that for every 2 cups of flour used, 1 cup of sugar should also be used. Another example might be a company's debt-to-equity ratio, which would compare the amount of debt they have to the amount of shareholder equity.
Ratios can be simplified or converted to percentages, decimals, or fractions to make them easier to work with.
