5.14 Comparing Fractions

Method:
  1. Read the fractions given.
  2. Arrange the fractions in either ascending or descending order.
  3. If the fractions are like, then we just compare the numerators.
  4. If the fractions are unlike, they are compared using LCM.
  5. Of the two fractions having the same denominator, the one with greater numerator is greater.
  6. Of the two fractions having the same numerator, the one with greater denominator is smaller.
Example: 1/7 _ 2/7
  1. The above is a pair of like fractions.
  2. Comparing the numerators, 1/7 < 2/7
Answer: <

Example: 5/3 _ 3/4

  1. The above is a pair of unlike fractions.
  2. Find the LCM of 3 and 4.
  3. LCM is 12.
  4. We then compare 20/12, 9/12.
  5. Hence 5/3 > 3/4.
Answer: >
