First we can understand problam by as 1/3 means 1 part form the 3 parts so it may some less value accound to other factor so the 1/3 will not come first fraction so 6/7 mean 6 parts so remaing is one part is '1' so it is highest value so the descending order is right.

Just divide and see the first and last numbers we will get as. 333 for 1/3, . 857 for 6/7. So, from this we can judge the answer easily.

1/6=..1616,1/3=.3333 etc and so on and similarly 5/6=5*.161616=0.8333 therfore just memorize 1/n ...till n=11....u can prdict the ANSWER DIRECTLY

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).

6/7=36/42.

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).
