In this lesson, we learn how to solve rational equations that are proportions. We are reminded that we need to multiply both sides by the least common denominator to get an equation without fractions. We are also shown how to alter non-proportion rational equations slightly to make them look like proportions. Additionally, we see how to solve quadratic equations that result from simplifying proportions, with the reminder that we can never have a zero in the denominator.
