Question

51) Which of the following fraction is the smallest?
(A) 11/13 -
(B) 9/11
(C) 3/4
(D) 5/7​

Answer 1

• To find this we have to equalise the denominators, i.e making their denominators same.

• To do so, we just need to find the LCM of their denominators, ie

LCM of 13,11,4,7 is 4004

• Now we just have to make denominators 4004 by multiplying it with suitable natural numbers, i.e after equalising the denominators we get,

3388/4004 ; 3276/4004 ; 3003/4004 ; 2860/4004 respectively.

So, now it's easy to find out the smallest fraction here, i.e 2860/4004 = 5/7 is the smallest among all the others

So, the correct option is d)

hope u got it....
