Proportion
Definition
Proportion refers to a relationship between two quantities that are equal or have a constant ratio.
Analogy
Think of baking cookies. If you double all the ingredients in a recipe, maintaining their ratios, you will end up with twice as many cookies. This demonstrates proportionality - changing one quantity affects another in a consistent way.
