(1/2), (5/4(, (2/3)
this is also (6/12), (15/12), and (8/12)
25 divided by that sum is 10.345, so that is the factor that each has to be multiplied by.
5.17
12.93
6.90
or 5.2 liters of A, 12.9 liters of B, and 6.9 liters of C.

A    :   B   :   C
1/2  :  5/4  :  2/3


Multiply all by 12.


6    :   15   :   8


The total parts by volume from the ratio done that way is 29.

Liters of A, B, C, to one decimal place:
A=%286%2F29%2925=5.2
B=%2815%2F29%2925=12.9
C=%288%2F29%2925=6.9
