# Ratio Problem

Find three 3-digit numbers in the ratio 3:2:1, using
each of the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 exactly once.

Well, the number 3 seems important here, so it's pretty obvious
that we should start with 3^{3} = 27.
Applying the ratio 3:2:1, gives 81, 54 and 27.
So far so good - we don't have any duplicated digits yet!
What's left over?
3, 6 and 9. Ok... let's just stick them on the front!

981, 654, 327
