Just take LCM of all and the fraction having smallest numerator is the largest number of all mentioned.

Numerator must be more than denominator to be higher value. From all of these options, D has numerator slightly somewhat higher than A, B C, so D is answer.

Consider the options A, B, C.
First 2 numbers are 1/3 and 2/5.
Multiply first with 5 and second with 3 then it becomes,
5/15 and 6/15:::: it is ascending order.
Hence option D is the correct answer.

Convert all into like fractions by taking their lCM, their LCM comes out to be 210 and then convert them according to their LCM and then we get the answer.

1/3 = 5/15.
2/5 = 6/15.
So option 1,2 & 3 will be wrong because of 5/15<6/15(not in descending order).
And for 4th one:
6/7=36/42.
5/6=35/42(so 6/7>5/6).
5/6=25/30.
4/5=24/30(so 5/6>4/5).
4/5=28/35.
3/7=15/35(so 4/5>3/7).
3/7=15/35.
2/5=14/35(so 3/7>2/5).
2/5=6/15.
1/3=5/15(so 2/5>1/3).
2/5 = 6/15.
So option 1,2 & 3 will be wrong because of 5/15<6/15(not in descending order).
And for 4th one:
6/7=36/42.
5/6=35/42(so 6/7>5/6).
5/6=25/30.
4/5=24/30(so 5/6>4/5).
4/5=28/35.
3/7=15/35(so 4/5>3/7).
3/7=15/35.
2/5=14/35(so 3/7>2/5).
2/5=6/15.
1/3=5/15(so 2/5>1/3).

Another shortcut to solve this que is to multiply numerator by 100 and simply dividing it with denominator like this:
100/3=33.3.
200/5=40.
300/7=42.8.
400/5=80.
500/6=83.3.
600/7=85.6.
Then we have the answer.
85.6>83.3>80>42.8>40>33.3.
Answer is 6/7 > 5/6 >4/5 > 3/7 > 2/5 > 1/3.
100/3=33.3.
200/5=40.
300/7=42.8.
400/5=80.
500/6=83.3.
600/7=85.6.
Then we have the answer.
85.6>83.3>80>42.8>40>33.3.
Answer is 6/7 > 5/6 >4/5 > 3/7 > 2/5 > 1/3.
