Understanding Rational Numbers and Fractions

This video tutorial by Mr. J explains how to order rational numbers using a number line. It covers the basic principles of number lines, such as the position of positive and negative numbers relative to zero. The tutorial includes two examples demonstrating how to convert fractions to decimals and place them on a number line to order them from least to greatest or greatest to least. The video emphasizes the importance of consistency in using either fractional or decimal forms for easier comparison.
