Proportions

Proportions describe a relationship between quantities where two ratios are equal. For example, if 2 apples cost $4, then a proportion helps us find out how much 5 apples would cost, maintaining the same price per apple. Think of it as a way to compare parts of a whole or different quantities that are related to each other proportionally. It allows us to solve for unknown values by setting up an equation where the ratios are equal, making it a useful tool in everyday problems, cooking, shopping, and more.
