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
