Rounding and Midpoint Concepts

The video tutorial explains how to round decimals using a number line. It provides two examples: rounding 7.237 to the nearest tenth and rounding 12.459 to the nearest hundredth. The tutorial demonstrates how to identify the position of a decimal on a number line and determine whether to round up or down based on its position relative to the midpoint.
