1. A/B=3
2. C/D=9

In both problems ( 1. and 2.) the union of the digits of numbers A & B (or C & D) is the full set of 9 non-zero decimal digits.

List all existing solutions.

(In reply to clarification needed? by Steve Herman)

Divide the set of 9 non-zero decimal digits into 2 disjoint subsets:
