If 9 is 3/7 of the entire quantity:
3
--- X = 9
7
So, via cross multiplication:
9 * 7 = 3X
63 = 3X
21 = X
The entire set is composed of 21 on units.
To check:
3
--- * 21 = 9 ; This statement is true, so 21 is correct.
7
A seventh is, in common math, 1 divided by 7. As this show, a full 7 sevenths would equate to 1. Thus, we can conclude that there is no way that 3 sevenths can be 9, as it is less than 7 sevenths.
3/5 * 15 = 9
3/7 x 21 = 9
9/3*5=15
9 = 3/7 x 21/1 = 63/7
9 = 3/7x 9 x 7/3 = x 9 x 2.333333 = x 21 = x The whole set is 21.

13 and 3/7
3/5 * 15 = 9
8/9
1/3
3/7 x 21 = 9
9/3*5=15
9 = (3/7)(x) multiply both sides by 7/3 (7/3)(9) = x 21 = x
4/9 is bigger than 3/7
9/21 is the same as 3/7.
(2/9) / (3/7) = (2/9) * (7/3) = 14/27
