Rafiq exercised = \(\frac{3}{6}\) of an hour.
Rohit exercised = \(\frac{3}{4}\) of an hour.
On comparing fractions \(\frac{3}{6}\) and \(\frac{3}{4}\) we get \(\frac{3}{4}\) \(>\) \(\frac{3}{6}\)
With equal numerators, the fraction with the smaller denominator gets the bigger slice of the pie..
Hence, Rohit exercised for a longer time.
