Explain the difference between a proportional relationship and a non-proportional relationship.

• A proportional relationship involves addition, while a non-proportional relationship involves multiplication.

• In a proportional relationship, the quantities are always equal, while in a non-proportional relationship, the quantities are never equal.

• The difference between a proportional relationship and a non-proportional relationship is that in a proportional relationship, the ratio between the two quantities remains constant, while in a non-proportional relationship, the ratio between the two quantities varies.

• The difference between a proportional relationship and a non-proportional relationship is that in a proportional relationship, the quantities increase at the same rate, while in a non-proportional relationship, the quantities increase at different rates.
