The video tutorial explains how to represent rational numbers on a number line using two methods: fraction representation and decimal conversion. It provides examples and practice exercises to help understand the concepts. The tutorial also covers identifying consecutive integers for given rational numbers, emphasizing the importance of understanding rational numbers in mathematics.
