What are the different kinds of proportions and its examples?

Answer 1

There are several types of proportions, including direct, inverse, and joint proportions. Direct proportion occurs when two quantities increase or decrease together, such as speed and distance (e.g., doubling speed doubles the distance traveled in a fixed time). Inverse proportion exists when one quantity increases while the other decreases, like the relationship between speed and travel time (e.g., increasing speed reduces travel time). Joint proportion involves multiple variables, where a quantity is directly proportional to the product of two or more other quantities, such as the volume of a gas being directly proportional to its temperature and the number of moles.
