What is an equavalent ratio?

Answer 1

An equivalent ratio is a ratio that expresses the same relationship between two quantities, even if the actual numbers differ. For example, the ratios 1:2 and 2:4 are equivalent because they represent the same proportional relationship. You can obtain equivalent ratios by multiplying or dividing both terms of the ratio by the same non-zero number. Equivalent ratios are often used in various applications, including scaling recipes and converting units.
