Check this technique:
In starting it may be consume some time but after practice we will solve in second.
6/7, 5/6, 4/5, 3/7, , 2/5, 1/7.
Check difference between numerator and denominator and then divide numerator with difference.
6-7 = 1.
6/1 = 6.
5-6 = 1.
5/1 = 5.
Don't confuse with numerator greater or smaller.
4-5 = 1.
4/1 = 4.
3-7 = 4.
3/4 = 0.7.
2-5 = 3.
2/3 = 0.6.
1-7 = 6.
1/6 = 0.1.

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.

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.

Let us check option D.
Write 6/7 = 60/7, 5/6 = 50/6, 4/5 = 40/5, and so on it makes easy to calculate. Since we converted them into improper functions.
8.5, 8.2, 8, 4.2, 4, 3.3

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.

Please tell me about it shortly.

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.

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