I did it by seeing just observe any numbers with same denominators like I supposed 7 denominator for option A I saw that 3/7 is coming before then 6/7 so option A is not in descending order, like as I tried B & C, lastly I got D which is correct for my consideration.

For the first three option take the 1st and last digit, then compare the two digit.
For option a), b)and c)
1/3=0.3333 and 6/7=0.8571, now we can see that 1st one is smaller then last one.
So they are not in descending order.
Hence answer is the rest means option D).

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.

First take the LCM of the denominators and the LCM is 210. Which is taken to common denominator do the numerators equal to 210 by multiplying the required numbers. By comparing we get the answers.
Thanks for creating this site this helps me very much.

Observe the all options in numerators and denominators.
If numerators increases value increases. But they are asking for decreasing order.
So denominator decreases the value decreases.
So there is only one option 6, 5, 4, 3, 2, 1.
So option: D.

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.

Take LCM for the Decimals: 3, 5, 7, 5, 6, 7.
The LCM is 3*5*6*7.
Now multiply each number with (2*3*5*7)/(3*5*6*7).
We will get the numerator values as 70, 84, 90, 168, 175, 180.
No the decreasing order is : 6/7, 5/6, 4/5,3/7,2/5, 1/3.

The fastest method of solving this prblm is converting each fraction into decimal.
Instead of finding LCM, it consumes lot of time.
And as terms if fraction are easy we can solve orally in few seconds.

The fraction whose numerator after cross multiplication gives the greater value is greater.
Here take the 1st two 6/7 and 5/6
6*6>5*7.
From given options option D only satisfy this...So ans is D.

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.
