Note 8

The difference between absolute and relative reasoning is critical to the study of proportions. It is important to understand that any additive situation is absolute and cannot be a proportion. All proportions are relative and relate the change to the original; thus, they are multiplicative. For example, "Jill has three more brothers than Kim" is an absolute and additive relationship and is not a proportion. "Kari has twice as many brothers as Leanne" is a relative and multiplicative relationship and is a proportion.
