Comparing and Ordering Rational Numbers on a Number Line

The video tutorial by Mr. J covers how to compare and order rational numbers using a number line. It begins with an introduction to the concept, explaining the position of positive and negative numbers relative to zero. The tutorial then demonstrates comparing positive and negative numbers, as well as fractions and decimals, using a number line. Finally, it explains how to order rational numbers from least to greatest and vice versa, providing examples for clarity.
