Question

Rafiq exercised for 3/6 of an hour, while rohith exercised for 3/4 who exercised longer

Answer 1

LCM of 6 and 4 is 12

3/6=3x2/6x2=6/12

3/4=3x3/4x3=9/12

hence, 9/12>6/12

therefore 3/4>3/6

it means rohith exercised more than rafiq. ANS.

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.
