Representing, Comparing, and Ordering Decimals

3-1

Line up the decimal points.

Start from the left and compare the digits.

Look for the first place where the digits are different.

Course 1

Additional Example 2: Earth Science Application

The star Wolf 359 has an apparent magnitude of 13.5. Suppose another star has an apparent magnitude of 13.05. Which star has the smaller magnitude?

13.50

13.05

0 is less than 5.

13.05 < 13.50

The star that has an apparent magnitude of 13.05 has the smaller magnitude.

Representing, Comparing, and Ordering Decimals

3-1

Line up the decimal points.

Start from the left and compare the digits.

Look for the first place where the digits are different.

Course 1

Try This: Example 2

Tina reported on a star for her science project that has a magnitude of 11.3. Maven reported on another star that has a magnitude of 11.03. Which star has the smaller magnitude?

11.30

11.03

0 is less than 3.

11.03 < 11.30

The star that has a magnitude of 11.03 has the smaller magnitude.

Representing, Comparing, and Ordering Decimals

3-1

Compare two of the numbers at a time.

Write 16.6 as “16.60.”

Start at the left and compare the digits.

Look for the first place where the digits are different.

Course 1

Additional Example 3: Comparing and Ordering Decimals

Order the decimals from least to greatest.

16.67, 16.6, 16.07

16.67

16.60

16.60 < 16.67

16.67

Course 1

Additional Example 3 Continued

Graph the numbers on a number line.

16.6

16.67
