👉 Rates and proportionality, or rates math, is a branch of mathematics dealing with the study of how quantities change in relation to each other. It involves understanding and calculating rates of change, such as speed (distance over time), growth rates (change in quantity over time), and proportional relationships (where one quantity changes at a constant rate relative to another). Key concepts include linear functions, where rates are constant and represented by slope; inverse proportionality, where one rate decreases as the other increases; and more complex relationships like exponential growth or decay, which describe rates that change at a rate proportional to their current value. This field is crucial in various applications, from physics and engineering to economics and biology, helping model and predict real-world phenomena.
