Understanding Rational and Irrational Numbers

The video tutorial explains the difference between rational and irrational numbers. Rational numbers can be expressed as fractions and have a repeating or terminating decimal pattern. Irrational numbers, like the square root of 10 or Pi, have non-repeating, non-terminating decimals. The tutorial uses examples such as square roots and Pi to illustrate these concepts, emphasizing that irrational numbers cannot be predicted or expressed as simple fractions.
