A rate is derived from taking 2 different quantities and through partitive division evaluating them to find a single unit measure such as price per one ice cream cone or distance per mile.
Also, I am glad I am not the only math major who made it through college without knowing there were 2 kinds of division. I will look at your resources to understand them better, which will then help my understanding of rates.
Also, I love the language of “scaling in tandem” rather than “x varying per y.” Such a good, visual description!
