Question

define direct and inverse proportion​

Answer 1

Answer:

In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion.

Answer 2

A direct and inverse proportion are used to show how the quantities and amount are related to each other. ... For example, if we say, a is proportional to b, then it is represented as 'a∝b' and if we say, a is inversely proportional to b, then it is denoted as 'a∝1/b'.
