Question 9 :
Rafiq exercised for 36 of an hour, while Rohit exercised for 34 of an hour. Who exercised for a longer time?
As per the question
Rafiq exercised 36 of an hour.
Rohit exercised 34 of an hour.
Now, the LCM of 6 and 4 is 12.
Therefore the equivalent fractions of 36 and 34 with the same denominator are:
36=3×26×2=612 and 34=3×34×3=912.
612<912
Therefore 34>36
Therefore, Rohit exercised for a longer time.
