What does porportion mean in math?

In math, a proportion is an equation that states two ratiOS are equal. It expresses the relationship between two quantities, often written in the form a/b = c/d, where a, b, c, and d are numbers. Proportions are used to solve problems involving scaling, comparisons, and finding unknown values in equivalent ratiOS. They are fundamental in various fields, including geometry, algebra, and statistics.
