Q.9 Rafiq exercised for \(\frac{3}{6} \)of an hour, while Rohit exercised for \(\frac{3}{4} \) of an hour. Who exercised for a longer time?


Answer :

Rafiq exercised for\(\frac{3}{6} \) of an hour.
Rohit exercised for \(\frac{3}{4} \) of an hour.
\(\frac{3}{6} \) and \(\frac{3}{4} \)
by cross multiplication
3 x 4 = 12 and 3 x 6 = 18
Since 12 < 18
\(\therefore \frac{3}{4} > \frac{3}{6} \)
Hence Rohit exercised for longer time.
