In a proportional relationship, the values for one quantity are each multiplied by the same number to get the values for the other quantity. This number is called the constant of proportionality. In this example, the constant of proportionality is 3, because 2 ⋅ 3 = 6 2 ⋅ 3 = 6, 3 ⋅ 3 = 9 3 ⋅ 3 = 9, and 5 ⋅ 3 = 15 5 ⋅ 3 = 15.

Here is a graph that represents different amounts that fit the situation, “Blueberries cost $6 per pound.”. Figure 2.4.1.1 2.4.1. 1. Different points on the graph tell us, for example, that 2 pounds of blueberries cost $12, and 4.5 pounds of blueberries cost $27. Proportion says that two ratios (or fractions) are equal. Example: We see that 1-out-of-3 is equal to 2-out-of-6. The ratios are the same, so they are in proportion. Example: Rope. A rope's length and weight are in proportion.
