20. 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 Line up the decimal points. Start from the left and compare the digits. 13.05 Look for the first place where the digits are different. 0 is less than 5. 13.05 < 13.50 The star that has an apparent magnitude of 13.05 has the smaller magnitude. Course 1 3-1 Representing, Comparing, and Ordering Decimals

21. 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 Line up the decimal points. Start from the left and compare the digits. 11.03 Look for the first place where the digits are different. 0 is less than 3. 11.03 < 11.30 The star that has a magnitude of 11.03 has the smaller magnitude.
