Then/Now You have already divided positive fractions and multiplied rational numbers. (Lesson 3–3) Divide positive and negative fractions using multiplicative inverses. Divide algebraic fractions.
Vocabulary multiplicative inverse reciprocal Two numbers whose product is 1. Another name for multiplicative inverse (you flip the fraction so the numerator and denominator switch places)
