We highlight how natural numbers (like 1, 2, 3), whole numbers (including 0), and integers (positive and negative) all qualify as rational numbers because they can be expressed with a denominator of 1. Through clear examples and visual explanations, this video helps students understand how rational numbers extend across familiar number sets and why expressing them in standard form makes comparison and computation easier.
