Direct Proportion in Mathematics
Direct Proportion, also known as direct variation, describes the direct relationship between two variables. In this direct relationship, when one variable increases in value, the other variable also increases, and conversely, when one variable decreases, the other variable decreases as well. This means that as one variable goes up or down, the other follows suit, maintaining a consistent and proportional change.
In simple words, Direct Proportion is the relation between two quantities where the ratio of the two is equal to a constant value. Direct Proportion is represented by a proportional Symbol i.e.,∝. In this article, we are going to learn direct proportion or direct variation in detail. It is an important concept of mathematics.
