Question:
The sum of the two numbers is $\frac{5}{9}$. If one of the numbers is $\frac{1}{3}$, find the other.
Solution:
It is given that the sum of two numbers is $\frac{5}{9}$, where one of the number $s$ is $\frac{1}{3}$.
Let the other number be $x$.
$\therefore \quad x+\frac{1}{3}=\frac{5}{9}$
$\Rightarrow x=\frac{5}{9}-\frac{1}{3}$
$\Rightarrow x=\frac{5}{9}-\frac{3}{9}$
$\Rightarrow x=\frac{5-3}{9}$
$\Rightarrow x=\frac{2}{9}$
