The video tutorial explains how to compare decimal numbers using a place value chart. It introduces the concept of place value, demonstrates how to arrange numbers in a chart, and provides examples of comparing decimals by examining digits from left to right. The lesson concludes with a summary of the comparison process.

• To multiply them accurately

• To add them more easily

• To convert them into fractions

• To determine which number is larger or smaller

What is the primary tool used to compare decimal numbers in this lesson?

• The ones place

• The tenths place

• The tens place

• The hundredths place

How do you start comparing two decimal numbers using a place value chart?

• By adding the digits together

• By subtracting the digits

• By comparing the digits from right to left

What should you do if the digits in the ones place are the same for both numbers?

• Compare the digits in the tenths place

• Multiply the digits

• Stop comparing

• Add the digits together

In the first example, what was the conclusion when comparing the numbers 658 thousandths and 659 thousandths?

What symbol is used to show that one decimal number is less than another?

• Equal to symbol

• Greater than symbol

• Less than symbol

• Plus symbol

In the second example, what was the first step in comparing the two decimal numbers?

• Compare the hundredths place

• Compare the tenths place

• Compare the thousandths place

• Compare the whole number part

If the whole number parts of two decimals are the same, what should you compare next?

• The thousandths place

• The tenths place

• The hundredths place

• The ones place

In the second example, which digit was greater in the tenths place?

• The bottom digit

• The top digit

• Both were equal

• Cannot be determined
