The lesson covers examples of finding reciprocals, as well as using them to solve equations by multiplying both sides of the equation by the reciprocal of the fraction. The lesson also emphasizes the importance of using reciprocals instead of dividing by fractions to avoid potential errors.

Staff Review
Great for learning about reciprocals and why it is important to use them. Many example problems are done in this video. A very good tutorial if you cannot seem to solve equations correctly, or if you have trouble trying to divide by fractions.
