What is the difference between a rational expression and equation? How do you find the least common denominator in rational problems? Use examples as needed to illustrate the steps.

Create one rational expression and one rational equation for your classmates to simplify/solve. Return to the Discussion to check your peers’ understanding and offer help as needed. Be sure to post the answers at the close of the module.
