Ex. Rafiq exercised for 3

6of an hour, while Rohit exercised for

3

4of an hour . Who exercised for a longer time?

Time taken by Rafiq for exercise = 3

6of an hour =

3

6of 60min

3

6x 60 min

= 30min.

Time taken by Rohit for exercise = 3

4of an hour =

3

4of 60min =

3

4x 60min

= 45min.

Therefore , Rohit exercised longer time to exercise.

Since 3

6and

3

4are unlike fractions with same numerators , the fraction with the smallest

denominator is greater. Therefore Rohit exercised longer time than Rafiq
