Lesson 1.01 Rational and Irrational Numbers

 

Overview

The goal of this lesson is to identify rational and irrational numbers.

You might remember that a ratio can be expressed as x out of y.  Knowing ratios are simply fractions stated differently we could express the same number as the fraction x/y (where y is not 0).

Rational numbers can be expressed as a ratio of two integers, or a fraction (whether proper or improper). Irrational numbers cannot be expressed as a ratio of two integers, or a fraction.

 

By the end of this lesson you will be able to differentiate between rational and irrational numbers and provide a reasonable rational estimate for irrational numbers.
