subtractthem

Step-by-step explanation:

Answer 2

Time taken by Javed: 2 2/5 minutes
: (2 x 5 + 2) / 5
: 12 / 5

Time taken by Rahul: 2 1/4 minutes
: (2 x 4 + 1) / 4
: 9 / 4
LCM of 4 and 5: 4 x 5
: 20

9 x 5 /4 x 5 = 45 / 20
12 x 4/ 5 x 4 = 48 / 20

45 < 48
48-45/20 = 3/20

So, Javed taks more time by 3/20 minutes.
You could also do this by Doing the above except it could be for 2/5 and 1/4
Hope it helped
