Comparing and Ordering Decimals

This video tutorial explains how to compare and order decimals using two main methods: comparing place values from left to right and equalizing the number of decimal places. It provides examples to illustrate both methods and demonstrates how to order a list of decimals from least to greatest. The tutorial emphasizes the importance of aligning place values and ensuring the same number of decimal places for accurate comparison.

What is one method to compare decimals?

• By comparing the sum of the digits

• By comparing the place values from left to right

• By comparing the place values from right to left

• By comparing the number of digits

How can you make decimals easier to compare?

• By converting them to fractions

• By removing zeros from the decimal

• By adding zeros to the left of the decimal

• By adding zeros to the right of the decimal

When comparing 5.22 and 5.219, which is greater?

• 5.22

• 5.219

• They are equal

• Cannot be determined

What is the first step in ordering decimals from least to greatest?

• Convert them to fractions

• Line them up vertically by decimal point

• Add zeros to the left

• Subtract the smallest from the largest

Which decimal is the smallest: 5.09, 5.085, 5.1, or 5.12?

• 5.1

• 5.085

• 5.09

• 5.12

How do you ensure all decimals have the same number of places?

• By converting to percentages

• By adding zeros to the right

• By removing zeros

• By adding zeros to the left

What is the largest decimal: 5.09, 5.085, 5.1, or 5.12?

• 5.085

• 5.09

• 5.1

• 5.12

In the second example, which decimal is the smallest: 12.008, 12.0098, 12.01, or 12.011?

• 12.01

• 12.0098

• 12.008

• 12.011

What is the purpose of adding zeros to decimals in the second example?

• To ensure they have the same number of decimal places

• To confuse the reader

• To convert them to fractions

• To make them look bigger

Which decimal is the largest in the second example: 12.008, 12.0098, 12.01, or 12.011?

• 12.01

• 12.011

• 12.0098

• 12.008
