COURSE 2 LESSON 3 10 Rational Numbers Compare

COURSE 2 LESSON 3 -10 Rational Numbers Compare – 1 and – 3. 4 8 Method 1 Since – 3 is farther to the left on the 8 number line, it is the lesser number. So, – 1 > – 3. 4 8 3 -10

COURSE 2 LESSON 3 -10 Rational Numbers (continued) Method 2 Rewrite – 1 with a – 1 in the numerator. – 1 = – 1 4 4 4 = – 1 2 The LCD is 8. Write an equivalent fraction. 4 2 – 2 2 2 = 8 =– 8 2 – 2 The fraction – 8 is equivalent to 8. 3 1 3 Since – 8 > – 8 , then – 4 > – 8. 3 -10

COURSE 2 LESSON 3 -10 Rational Numbers Compare. Use <, >, or =. a. 8. 7 and 8. 1 8. 7 > 8. 1 Both numbers are positive. Compare the digits. b. – 8. 7 and 8. 1 – 8. 7 < 8. 1 Any negative number is less than a positive number. c. – 8. 7 and – 8. 1 Place the decimals on a number line and compare their locations. – 8. 7 < – 8. 1 3 -10

COURSE 2 LESSON 3 -10 Rational Numbers Order these numbers from least to greatest: 3 2 – 5 , 0. 625, 3 , – 0. 5 3 – 5 = – 3 ÷ 5 = – 0. 6 Write as a decimal. 2 = 2 ÷ 3 = 0. 6 3 Write as a repeating decimal. – 0. 6 < – 0. 5 < 0. 625 < 0. 6 Compare the decimals. 3 2 From least to greatest, the numbers are – 5 , – 0. 5, 0. 625, 3. 3 -10

COURSE 2 LESSON 3 -10 Rational Numbers Compare. Use <, >, or =. 1. – 3 < 3. 3. 4 > – 3. 4 4 – 4 7 2. – 1 8 4. – 8. 9 3 -10 > – 3 8 < – 8. 6
