Direct Proportion Formula

About Direct Proportion Formula

A mathematical comparison between two numbers in which the ratio of the two numbers equals a fixed value is known as direct proportion. When two ratios are equal, they are in proportion, according to the proportion definition. The proportions are represented by the symbol "∝".

Direct Proportion Definition

"When the relationship between two quantities is such that if we increase one, the other will also rise, and if we decrease one, the other will similarly decrease, then the two values are said to be in a direct proportion," according to the definition. For example, suppose there are two values x and y, where x represents the number of candies and y represents the total amount of money spent. We will have to spend more money if we buy more candy, and we will pay less money if we buy fewer candies. As a result, we can argue that x and y are directly proportional. x ∝ y is the symbol for it. Direct variation is another name for direct proportion. More Maths Formulas on the parent's page.
