Question

Mahesh takes 2 1/5 minutes to walk around the school ground Suresh takes 7/4 minutes to do the same who's take less time and by what fraction

Answer 1

Hi friend Mahesh takes less time

Mahesh takes = 21/5 min
= 4.2 min
and Suresh takes = 7/4 min = 1.7 min

Hence Suresh takes less time than mahesh

Or
2nd method

To compare u have to makes their denominator equal
Lcm = 20

Mahesh = (21×4)/(5×4) = 84/20
and suresh = (7×5)/(4×5) = 35/20

so u can see that 84/20 > 35/20

So Suresh takes less time


Goodluck....
