Understanding Rational and Irrational Numbers

The video tutorial explains the difference between rational and irrational numbers, providing definitions and examples. Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot. The tutorial includes examples to identify these numbers, discusses the irrational side lengths of squares, and examines rational approximations of pi. A final practice problem helps reinforce the concepts.
