a/bc + d/ef + g/hi = 1
Each of three fractions has a one-digit numerator and a two digit denominator. The three fractions together add up to one. Place the nine digits 1-9 into the fractions to make the equation correct.

8/16 + 9/27 + 9/54 = 1. This is not what you are looking for, because 9 is used twice and 3 is not used. So, try other equivalent representations, until you hit one that uses all digits once. If you cannot find any, try other representations of 1, such as 1/2 + 1/4 + 1/4, or 1/3 + 1/3 + 1/3.Cheers,
