6. Compare the decimals. Write. Additional Example 2: Comparing Decimals 0.4270.425 0.427 0.425 0.427 > 0.425 Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: 7 5 7 > 5. Course 2 3-10 Comparing and Ordering Rational Numbers

7. Compare the decimals. Write. 0.5350.538 0.535 0.538 0.535 < 0.538 Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: 5 8 5 < 8. Try This: Example 2 Course 2 3-10 Comparing and Ordering Rational Numbers

8. Order the numbers from least to greatest. Additional Example 3: Ordering Fractions and Decimals 4545 0.93, and 0.9, 4545 = 0.80 Graph the numbers on a number line. 0 0.2 0.4 0.6 0.8 1 0.93 Write as decimals with the same number of places. 0.93 = 0.93 0.9 = 0.90 Course 2 3-10 Comparing and Ordering Rational Numbers

9. Additional Example 3 Continued The values on a number line increase as we move from left to right. 0.80 < 0.90 < 0.93 4545, 0.9, 0.93 Place the decimals in order. Order the numbers from least to greatest. 4545 0.93, and 0.9, 0 0.2 0.4 0.6 0.8 1 0.93 Course 2 3-10 Comparing and Ordering Rational Numbers

10. Order the numbers from least to greatest. Try This: Example 3 3535 0.84, and 0.7, 3535 = 0.60 Graph the numbers on a number line. 0 0.2 0.4 0.6 0.8 1 0.84 Write as decimals with the same number of places. 0.84 = 0.84 0.7 = 0.70 Course 2 3-10 Comparing and Ordering Rational Numbers

11. Try This: Example 3 Continued The values on a number line increase as we move from left to right. 0.60 < 0.70 < 0.84 3535, 0.7, 0.84 Place the decimals in order. Order the numbers from least to greatest. 3535 0.84, and 0.7, 0 0.2 0.4 0.6 0.8 1 0.84 Course 2 3-10 Comparing and Ordering Rational Numbers
