Proportion

Definition

Proportion refers to the relationship between quantities, where a change in one quantity results in a corresponding change in another. It is a fundamental concept that can be used to compare the sizes, amounts, or values of different things, often expressed mathematically through ratios. This concept is crucial in various fields, particularly in mathematics and art, where it helps in achieving balance and harmony in compositions.
