Comparing and Ordering Decimals

This video tutorial teaches how to order decimals from least to greatest and greatest to least. It provides step-by-step examples, demonstrating how to align decimal points and compare numbers by place value. The tutorial includes practice exercises to reinforce learning, ensuring students understand the process of ordering decimals accurately.

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

• Cross out the largest number first.

• Compare the numbers directly.

• Stack the numbers and align the decimal points.

• Add placeholder zeros.

When comparing decimals, which place value should you start with?

• Any place value.

• The smallest place value.

• The largest place value.

• The middle place value.

In the example of ordering 4.56, 4.562, 4.558, and 4.65, which number is the largest?

• 4.558

• 4.65

• 4.562

• 4.56

What should you do if two numbers have the same digit in a place value?

• Cross them out and move to the next place value.

• Add a placeholder zero.

• Choose one randomly.

• Stop comparing.

In the example of ordering 56.30, 65.30, 56.299, and 56.305, which number is the smallest?

• 56.305

• 56.299

• 65.30

• 56.30

How do you determine the order of numbers when they have the same digits in the largest place value?

• By guessing.

• By subtracting them.

• By comparing the next largest place value.

• By adding them together.

In the example of ordering 2.58, 2.85, and 2.578, which number is the largest?

• They are all the same.

• 2.578

• 2.85

• 2.58

What is the correct order from least to greatest for the numbers 2.578, 2.58, and 2.85?

• 2.85, 2.58, 2.578

• 2.58, 2.578, 2.85

• 2.578, 2.58, 2.85

• 2.578, 2.85, 2.58

In the practice exercise, which number is the smallest: 1.578, 1.758, 1.57, or 1.563?

• 1.758

• 1.578

• 1.563

• 1.57

What is the correct order from least to greatest for the numbers 1.578, 1.758, 1.57, and 1.563?

• 1.563, 1.57, 1.578, 1.758

• 1.758, 1.578, 1.57, 1.563

• 1.57, 1.563, 1.758, 1.578

• 1.578, 1.563, 1.758, 1.57
