Finding Rational Numbers

The video tutorial focuses on rational numbers, explaining their importance and methods to find them between integers and fractions. It covers three main methods: finding equidistant rational numbers, using ratios, and the midpoint method. The tutorial also discusses the concept of rational numbers between fractions using LCM and highlights that rational numbers can have multiple representations. The session concludes with a preview of the next topic on converting repeating decimals to fractions.
