# Direct proportion versus inverse proportion

There are two proportions

## Proportion or direct proportion example

Apples are directly proportional to money

8 apples cost £4.00

and so 24 apples cost £12.00

## Inverse proportion example

The length of time to paint a room is inversely proportional to the number of people painting it.

3 people take 8 hours

4 people take 6 hours (i.e. less than 8 hours)
