Question

Rafiq exercised for 3/6 of an hour, while Rohit, Exercised for 3/4 of an hour. who exercised for a longer time and by what fraction of an hour?

Answer 1

Answer:

Rohit. By a fraction of 1/4th of an hour

Step-by-step explanation:

Rafiq exercised 3/6 of an hour, i.e 50% of an hour = 30 mins

Rohit exercised for 3/4th of an hour, i.e 75% of an hour = 45 mins

Difference in time exercised: 45-30 mins = 15 mins

15/60 = 1/4th of an hour

Thus Rohit exercised more than Rafiq by 1/4th of an hour

Answer 2

ՏϴᏞႮͲᏆϴΝ :-

Rafiq exercised for $\large \frac{3}{6}$ hours.

And, Rohit excercised for $\large \frac{3}{4}$ hours.

Now, $\large \frac{3}{6} = \frac{3 × 2}{6 × 2} = \frac{6}{12}$

and, $\large \frac{3}{4} = \frac{3 × 3}{4 × 3} = \frac{9}{12}$

$\large \: \: \frac{9}{12} > \frac{6}{12} \: i.e, \: \frac{3}{4} > \frac{3}{6}$

Thus, Rohit excercised for a longer time.
