Ratios and Proportions
A ratio compares two values, such as 2:3 or 16:9, while a proportion says two ratios are equal. People use ratio calculators for recipes, map scales, screen aspect ratios, dilution mixes, and math problems involving cross-multiplication.
How to Simplify a Ratio
To simplify a ratio, divide both sides by their greatest common factor. This makes the comparison easier to read while keeping the same relationship, which is helpful when resizing designs or scaling ingredients up and down.
