 2 pandigital equations (Posted on 2014-09-05)

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.

 clarification needed? | Comment 1 of 4
I think that this needs further clarification.

Part part 1, is 41152263 / 123456789 a valid solution?  If so, then there are an infinite number of solutions.

What if a number does not repeat within the numerator or denominator, but the same digit appears in both?  I think this is a solution, since the union of {1,2,3,4,5} and {5,6,7,8,9} is {1,2,3,4,5,6,7,8,9}.   And this is consistent with a finite number of solutions.
