1) Your API does not hide the implementation details. If we change the 
representation of an amount, many calls will have to be changed rather than 
localizing the changes to the "math" routines.

2) The "denominator" may need to be the reciprocal of an integer greater than 
unity.

3) There are no constraints to assure that the results remain in the 
allowable domain of values.

4) I have numerous objections related to efficiency and "cleanliness" of the 
interface, but they are not strictly complaints about "correctness" if you 
choose to define that to mean "sufficient to derive the correct answer".

There's more, but, frankly, I'm tired reirrerating them onto deaf ears.
When (if) you are willing to attempt to address the problems listed above, I 
will try to be more complete.
