Simply Multiply all value with 100 so that you will get the answers regarding 100
like 1/3*100, 2/5*100, 3/7*100, 4/5*100, 5/6*100, 6/7*100
Now taking the answers of all the values in decimal we will get the values as
33.33, 40, 42.84, 80, 83.35, 85.68
Now arranging the value in descending order we get as
85.68, 83.35, 80, 42.84, 40, 33.33
6/7, 5/6, 4/5, 3/7, 2/5, 1/3 right answer.

First cross multiply each term with adjacent next term. So we get a number series as follows.
Eg. take option D.
6*6 = 36
7*5 = 35
5*5 = 25
6*4 = 24
4*7 = 28
5*3 = 15
2*3 = 6
1*5 = 5
From this series we clear that it is in descending order.

6*6 = 36

1*5 = 5
From this series we clear that it is in descending order.

In option D only numerator are in descending order not in other easy and quick method.

If differences between the numerator and denominator is very low it means it having the high value of that fraction. In this 1/3, 1/5, 6/7 only 6/7 having less difference so series starts from here.
