The video tutorial explains the difference between rational and irrational numbers. It covers how rational numbers can be expressed as fractions, including integers, repeating decimals, and terminating decimals. The tutorial also defines irrational numbers, which cannot be expressed as fractions and lack repeating patterns, using examples like pi and the square root of two. It provides a step-by-step guide to determine if a number is rational or irrational.
