What term describes an equation stating that two ratios are equivalent?

The term that describes an equation stating that two ratios are equivalent is "proportion." A proportion demonstrates the relationship between two ratios, showing that they hold the same value when expressed as fractions. For example, if you have the ratios 1/2 and 2/4, you can express that as a proportion when you write it like this: 1/2 = 2/4. This indicates that both fractions simplify to the same decimal (0.5), showcasing the equality of the two ratios.

In contrast, the term "equation" refers to any statement that two expressions are equal, which encompasses a broader category than just proportions. "Relation" is a general term that could refer to various connections between numbers, pairs of values, or variables but does not specifically denote the equivalence of ratios. The word "comparison" suggests an analysis or evaluation of differences or similarities between two entities but does not inherently imply that these comparisons are equivalent ratios, which is the essence of a proportion. Thus, "proportion" is the most accurate term for describing an equation that states two ratios are equivalent.
