Solution
\[\text{It is given that the sum of two numbers is} \frac{5}{9}, \text{where one of the numbers is} \frac{1}{3} . \]
\[\text{Let the other number be x} . \]
\[ \therefore x + \frac{1}{3} = \frac{5}{9}\]
\[ \Rightarrow x = \frac{5}{9} - \frac{1}{3}\]
\[ \Rightarrow x = \frac{5}{9} - \frac{3}{9}\]
\[ \Rightarrow x = \frac{5 - 3}{9}\]
\[ \Rightarrow x = \frac{2}{9}\]
