Question

Ram exercised for 2/3 hour. while Rohit exercised for 3/ 4 hour. who exercised for a longer time?

Answer 1

1 hour = 60 minutes
RAM:
2/3 of an hour
=2/3 of 60
=40 minutes
ROHIT:
3/4 of an hour
=3/4 × 60
=45 minutes
therefore,Rohit exercised for longer time.

Answer 2

Ram exercised for=⅔ hours
Rohit exercised for=¾ hours

Taking the LCM of 3 and 4
3×4=12

Ram exercised for= 8÷12 hours
Rohit exercised for= 9÷12 hours

Hence, Rohit exercised more than Ram by 1/12 hours ,or, 5 minutes.

[1/12 hours=5 minutes]
