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.

Inversely Proportional: when one value decreases at the same rate that the other increases. Example: speed and travel time Speed and travel time are Inversely Proportional because the faster we go the shorter the time.
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.
In mathematics, two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio. The ratio is called coefficient of proportionality (or proportionality constant ) and its reciprocal is known as constant of normalization (or normalizing constant ).
Indirect proportion can be defined as the establishment of a relationship between two different quantities where an increase of a quantity leads to a decrease of the other quantity. It occurs when there is an inverse type of relationship present between two different quantities.
To determine the graph of a directly proportional relationship or an inversely proportional relationship, we need to understand how the two variables are linked and be able to sketch this on a set of axes.

Share : For some questions, you'll be given the general relationship between x and y, but you'll have to figure out exactly what the formula is. This relationship is either directly proportional, or inversely proportional.
