How is a ratio used as a scale? - Answers

A ratio can be used as a scale by expressing the relationship between two quantities, allowing for proportional comparisons. In maps or models, for example, a ratio scale indicates how many units in reality correspond to one unit on the representation, such as 1:100,000 meaning one unit on the map equals 100,000 units in real life. This enables users to accurately interpret distances and sizes in relation to actual measurements. Ratios thus provide a consistent framework for scaling various elements while maintaining their relative proportions.
