Here are the steps you can follow: Step 1: Understand the Concept of Proportional Relationships. A proportional relationship is one in which two quantities always have the same ratio.Proportional relationships in mathematics are often represented in equations and graphs. A proportional relationship is one in which the ratio of two variables is constant. This means that for any increase or decrease in one variable, there will be a corresponding increase or decrease in the other variable that keeps the ratio the same.
