Indirect proportion (inverse proportion) is a relationship between two quantities where as one quantity increases, the other quantity decreases and vice-versa. For example, it takes 11 worker 99 hours to dig a hole.

Directly proportional: as one amount increases, another amount increases at the same rate. ∝. The symbol for "directly proportional" is ∝. (Don't confuse it with the symbol for infinity ∞) Example: you are paid $20 an hour. How much you earn is directly proportional to how many hours you work.
In math, an inverse proportion is when an increase in one quantity results in a decrease in another quantity. This video will show how to solve an inverse proportion math problem. Example : The pressure in a piston is 2.0 atm at 25°C and the volume is 4.0L.
Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.
The direct proportion formula is y=kx. Directly proportional graphs can be straight line graphs. As the variable x increases, the y variable increases and so the straight line continues on the same gradient as x gets larger; conversely, the straight line tends to 0 as x and y get smaller.
When two variables are indirectly proportional to each other (also known as inversely proportional), they are related by an equation of the following form: xy = k. where k is a constant and x and y are variables. This equation may be re-written as y = k/x or x = k/y.
A direct and inverse proportion are used to show how the quantities and amount are related to each other. They are also mentioned as directly proportional or inversely proportional. The symbol used to denote the proportionality is ‘ ∝ ‘.
