Answer 2

Answer:

To show how quantities are related to each other, you use direct or inverse proportion or a proportional symbol. When two quantities X and Y increase together or decrease together, they are said to be directly proportional or they are in direct proportion with each other. It is also known as a direct variation. The ratio of these values will remain constant. But when quantities X and Y are inversely proportional to each other or in the inverse proportion, one quantity decreases when the other quantity increases or when one quantity increases the other quantity decreases. It is also known as inverse variation. The ratio of these values varies inversely.
