Lesson 4 6 comparing and ordering fractions

  1. 1. Name ___________________________________ Date _________________Mrs. Labuski / Mrs. Rooney Period _______ Lesson 4-6 Comparing& Ordering VOCABULARY DEFINITION EXAMPLE When fractions 7 3Like Fractions have the same 10 10 denominator. When two 2 3 Unlike fractions have 3 4 Fractions different denominators. To compare unlike 2 3 fractions you must 3 4 Common rename the fractions so they   Denominators have a common 8< 9 denominator. 12 12When you are comparing fractions, first check their denominators.When you have like fractions that have the same denominator you look at thenumerator to see which fraction is larger or smaller. 3 < 710 10When you have unlike fractions have to find a common denominator. 1 and 1To find the common denominator: 2 3You can multiply the denominators together to get 2 x 3 = 6a common denominator. (or find the least common 6 is your common denominatormultiple.)Find equivalent fractions using the new 1 = 3 1= 2denominator. 2 6 3 6Compare the fractions 3>2 6 6
  2. 2. Now let’s try some together:1. 2. 3.4. 5. 6.7. 8. 9.Hints:Change all to fractions with common denominators then solve orChange all to decimals and then solve.Write answer in original form.
