Correct Assignment: Back of blue worksheet and Page 204 #1-6 & 8-16 Today’s Plan: -Compare and order decimals -Compare and order fractions 11/29/10 Compare and Order Rational Numbers Learning Target: -I can convert, compare, and order fractions and decimals.

2
Retake Today’s Plan: -Compare and order decimals -Compare and order fractions 11/29/10 Compare and Order Rational Numbers Learning Target: -I can convert, compare, and order fractions and decimals.

3
Learn to compare and order fractions and decimals. Course 2 2-11 Comparing and Ordering Rational Numbers Vocabulary rational number

4
A rational number is a number that can be written as a fraction with integers for its numerator and denominator. When rational numbers are written in a variety of forms, you can compare the numbers by writing them all in the same form. Course 2 2-11 Comparing and Ordering Rational Numbers

5
Which is greater, or ? 7979 2929 When two fractions have the same denominator, just compare the numerators. 7979 > 2929 because 7 > 2. = 7979 = 2929 Course 2 2-11 Comparing and Ordering Rational Numbers

6
Compare the fractions. Write. Additional Example 1A: Comparing Fractions 7979 5858 7979 = 7 · 8 9 · 8 = 56 72 5858 = 5 · 9 8 · 9 = 45 72 56 72 > 45 72, and so. 7979 > 5858 Write equivalent fractions with 72 as the denominator. Course 2 2-11 Comparing and Ordering Rational Numbers Compare the numbers.

7
Additional Example 1B: Comparing Fractions Compare the fractions. Write. 2525 3737 – – 2525 – = –2 · 7 5 · 7 = –14 35 3737 – = –3 · 5 7 · 5 = –15 35 – 14 35 > – 15 35, and so – >. 2525 – 3737 Write equivalent fractions with 35 as the denominator. Put the negative signs in the numerators. Both fractions can be written with a denominator of 35. Course 2 2-11 Comparing and Ordering Rational Numbers

8
Compare the fractions. Write. 5656 7878 The LCM of the denominators 6 and 8 is 48. 5656 = 5 · 8 6 · 8 = 40 48 7878 = 7 · 6 8 · 6 = 42 48 40 48 < 42 48, and so. 5656 < 7878 Write equivalent fractions with 48 as the denominator. Check It Out: Example 1A Course 2 2-11 Comparing and Ordering Rational Numbers Compare the numerators.

9
Compare the fractions. Write. 6868 5757 – – 6868 – = –6 · 7 8 · 7 = –42 56 5757 – = –5 · 8 7 · 8 = –40 56 – 42 56 < – 40 56, and so – <. 6868 – 5757 Write equivalent fractions with common denominators. Put the negative signs in the numerators. Check It Out: Example 1B Both fractions can be written with a denominator of 56. Course 2 2-11 Comparing and Ordering Rational Numbers

10
Course 2 2-11 Comparing and Ordering Rational Numbers The values on a number line increase as you move from left to right. Remember!

11
Order Additional Example 3: Ordering Fractions and Decimals 4545 0.93, and 0.9 from least to greatest., 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 2-11 Comparing and Ordering Rational Numbers 0.80 < 0.90 < 0.93Compare the decimals in order. 4545 From least to greatest, the numbers are, 0.9, 0.93.

12
Order, 0.84, and 0.7 from least to greatest. Check It Out: Example 3 3535 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 2-11 Comparing and Ordering Rational Numbers 0.60 < 0.70 < 0.84Compare the decimals in order. 3535 From least to greatest, the numbers are, 0.7, 0.84.
