One equation with nine unknowns! (Posted on 2006-12-13) Difficulty: 4 of 5

Solve the given equation by using the integers from 1 to 9 inclusive exactly once each.

a/(b*c)+d/(e*f)+g/(h*i)=1

Note: Obviously this problem is easily susceptible to a brute force approach - however, it would be nice to see some arguments that don't use computer programs!

Thanks for this, Steve - I really have been struggling with the problem.

By making this comment, I have no wish to denigrate the puzzle.

Thanks, John - it really is a great one!

:-) Josie
