Understanding Decimals on a Number Line

The video tutorial explains how to plot decimals on a number line. It begins with plotting decimals between 0 and 1, specifically focusing on 0.7. The tutorial then demonstrates dividing the interval into subintervals of 0.1. Next, it introduces the concept of hundredths place value, using 2.14 as an example, and shows how to divide intervals into hundredths. Finally, it plots 2.14 on the number line, illustrating the process of identifying and marking decimal values accurately.
