Identifying Rational Numbers

The video tutorial explains rational numbers, which are numbers that can be expressed as fractions where the denominator is not zero. It covers the relationship between ratios and fractions, and how whole numbers, fractions, mixed numbers, and decimals can be rational numbers. The video also distinguishes between rational and non-rational numbers, using pi as an example of a non-rational number. It concludes by summarizing the characteristics of rational numbers, including whole numbers, fractions, mixed numbers, and both terminating and repeating decimals.
