Compare the decimals. Write. Additional Example 2: Comparing Decimals > Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: > 5. Course Comparing and Ordering Rational Numbers

Compare the decimals. Write < Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: < 8. Try This: Example 2 Course Comparing and Ordering Rational Numbers

Order the numbers from least to greatest. Additional Example 3: Ordering Fractions and Decimals , and 0.9, 4545 = 0.80 Graph the numbers on a number line Write as decimals with the same number of places = = 0.90 Course Comparing and Ordering Rational Numbers

Additional Example 3 Continued The values on a number line increase as we move from left to right < 0.90 < , 0.9, 0.93 Place the decimals in order. Order the numbers from least to greatest , and 0.9, Course Comparing and Ordering Rational Numbers

Order the numbers from least to greatest. Try This: Example , and 0.7, 3535 = 0.60 Graph the numbers on a number line Write as decimals with the same number of places = = 0.70 Course Comparing and Ordering Rational Numbers

Try This: Example 3 Continued The values on a number line increase as we move from left to right < 0.70 < , 0.7, 0.84 Place the decimals in order. Order the numbers from least to greatest , and 0.7, Course Comparing and Ordering Rational Numbers
