Let \(W, X, Y,\) and \(Z\) be four different digits selected from the set  

\(\{ 1,2,3,4,5,6,7,8,9\}.\)  

Find the smallest possible value of the sum \(\frac{W}{X} + \frac{Y}{Z}\). The original answer is in the format \(\frac{m}{n}\). Please provide the value of \(m + n\).

Let's think step by step and output the final answer within \boxed{}.
