Two variables are said to be in inverse proportion if their product is a constant.
So, if X and Y are in inverse proportion, then
XY = k or Y = k/X for some constant k.
If you double X then Y is halved. If you decrease X by a factor of 3 then Y is trebled.
A common example is Speed and Time for covering a fixed Distance.

What is inverse proportion?
Inverse proportion is when one value increases, as the other decreases. For example the number of builders building a wall and the number of days it takes to build a wall are 2 quantities in inverse proportion because the more builders there are, the less time it takes to build the wall (there are more people working on it, so it will be built quickly). As the number of builders increases, the number of days to build the wall decreases. This is inverse proportion.
