Welcome to Math-Center.Org’s learning hub on Ratios! Ratios are a fundamental concept in math that help us compare quantities and understand relationships between numbers. Whether you're dividing a recipe, analyzing data, or solving real-world problems, ratios play a key role in daily life and academic success. In most school curricula, understanding ratios typically begins in upper elementary and middle school (Grades 6–8), forming the foundation for more advanced topics like proportions, rates, percentages, and algebra.
