A proportional relationship is a relationship between two variables where the ratio of one variable to the other variable is constant.

Proportional relationships demonstrate the concept of equivalent ratios. They are known as such because one always stays constant relative to the other.

That constant is called the “constant of proportionality”. Both variables can vary, and they just continue multiplying each other.

What is a proportional relationship?

A proportional relationship exists when, during changes to one variable, another variable connected with it changes by the same proportion.

A proportional relationship is when two quantities are proportional to one another. For example, if you divide the temperature by 3, then the original temperature is three times as big. A proportional relationship can be written as a fraction.

Examples of proportional relationships

A proportional relationship is a type of relationship where the ratios between two quantities are constant.

For example, if one person has 1/4 as much money as another person, then the ratio between their wealth is 1:4. The proportions in a proportional relationship can also be expressed as fractions.

What is a proportional relationship?

One way to show proportional relationships is by drawing a graph of two variables. The values are plotted on the coordinate plane, with one variable’s value on the x-axis and the other’s value on the y-axis.

You can quickly determine the type of relationship in a table using ratios. When each ratio is the same, it’s proportional and when ratios differ, they’re not proportional.

What proportion can I expect to experience in the fields of relationships, jobs, money, fields of study, jobs?

Inverse proportions

A proportional relationship is when two variables change in the same ratio. For example, if you increase one variable by 10%, the other will also increase by 10%. Proportional relationships are not only limited to numbers and units of measurements.

For example, a proportional relationship between Newton’s formula and the law of gravity is the product of mass and gravitational forces which is equal to constant formula_1.
