Proportions show up in many different careers. The worker in this photograph is carefully adding a small amount of one chemical into a flask containing another chemical. Getting the proportions of chemicals correct can be a matter of life and death.

 

In this lesson you explored how to use proportional reasoning and unit analysis to solve problems. You found that a variety of different strategies can help you solve rate problems.
