Rational Numbers and their location on a Number Line

Courses Overview

🎬 Video Tutorial

  • (0:01) What Are Rational Numbers?: Rational numbers are numbers that can be written as a fraction of two integers (a/b) where b ≠ 0.
  • (0:17) Examples of Rational Numbers: Fractions like 2/3, integers like -2, terminating decimals like 0.7, and recurring decimals like 0.3 recurring (1/3) are all rational numbers.
  • (1:13) What are Irrational Numbers: Irrational numbers cannot be expressed as a fraction and have non-terminating, non-repeating decimals. For example, $\pi$ and $\sqrt{2}$ .
  • (2:21) Locating Rational Numbers on a Number Line: Start at 0, move the whole number part first, and then move the fractional part.
