The concept of multiplying the numerators and the denominators of fractions also applies to multiplying rational algebraic expressions. For example, the distance in the previous activity is solved by multiplying the numerators and denominators of the speed and time of travel. In addition to just multiplying the numerators and denominators, there are methods of reducing the product into its lowest forms. Multiplying rational algebraic expressions and methods of reducing the product in lowest form will be discussed using series of examples.​
