Finding and Using the Multiplicative Inverse

This video tutorial explains the concept of the multiplicative inverse, also known as the reciprocal. It highlights the difference between the multiplicative inverse and the multiplicative identity, which is 1. The tutorial provides examples of finding the multiplicative inverse of fractions and mixed numbers by interchanging the numerator and denominator. It also demonstrates how to use the multiplicative inverse to write equivalent expressions, particularly in the context of dividing fractions.
