🎬 Video Tutorial

(0:01) Definition of 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) 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.
