The video tutorial explains how to compare decimal numbers using a place value chart. It begins by introducing decimal numbers and their common uses, such as in money and measurements. The tutorial then demonstrates how to align decimal points and compare digits in a place value chart, using the example of sprint times in a 100-meter dash. The process involves identifying differences in decimal places to determine the fastest and slowest times. The video concludes by encouraging further practice with comparing decimals.
