Comparing and Understanding Decimals

This video tutorial teaches how to compare and order decimal numbers up to the thousandths place by examining digits from left to right. It explains the base-10 number system and how place values decrease or increase by an order of 10. The tutorial uses the example of dividing a dollar into tenths, hundredths, and thousandths to illustrate decimal fractions. It demonstrates comparing numbers like 3.599 and 3.609 by analyzing digits in the same place value. The video also includes a practical example of ordering gas prices to reinforce the concept. By the end, viewers will understand how to compare and order decimals by treating them as fractions.
