Method
  1. When the denominators are common we simply compare the numerators.
  2. When the denominators are different, we find Least Common denominator and then compare the numerators.
Example: Which is bigger 1/2 or 1/5
In the above problem the denominators are different.
Denominators are made common.
List out the multiples of 2 - 2,4, 6, 8,10.
List out the multiples of 5 - 5, 10, 15, 20.
Common multiple is 10 and hence the LCM.
Multiply and divide each fraction by the LCM
1/2 x 10/10 = 5/10
1/5 x 10/10 = 2/10
The denominators are made common.
Hence 1/2 = 5/10 and 1/5 = 2/10
Hence 1/2 is greater than 1/5
Answer: 1/2
