LESSON 1-1 Rational Numbers IrrationalWhen multiplying rational expressions the thing you should pay attention to is reducing fractions and shortening expressions before you start multiplying. This will significantly shorten the time it will take for you to solve the task that has been given to you. Example 1. Multiply and reduce $15ab \cdot \frac{a}{3b}$

Now we are going to begin multiplying rational expressions. Let's go back a bit and review multiplying rational numbers, because rational numbers and rational expressions have a lot in common." - "First, let's just review what a rational number is. A rational number can be written in fraction form, and the denominator is never 0.

The goal of this lesson is to familiarize the reader with the properties of operations of rational numbers, and before that, how we construct and define this specified set. Rational numbers. On the set of natural numbers we could not define the operation $’-‘$ for all two natural numbers.
