Here's a simple way to think about it:
* Imagine a recipe for cookies: If you double the amount of flour, you also need to double the amount of sugar to keep the cookies tasting the same. The amount of flour and sugar are *proportional* to each other.
* Another example: If you increase the speed of a car, the distance it travels in a given time will also increase proportionally.
Key points about proportionality:
* Direct Proportion: When two quantities increase or decrease together at the same rate. (More flour = more cookies)
* Inverse Proportion: When one quantity increases as the other decreases. (More workers = less time to complete a task)
