Question:
The sum of two numbers is $\frac{-1}{3}$. If one of the numbers is $\frac{-12}{3}$, find the other.
Solution:
It is given that the sum of two numbers is $\frac{-1}{3}$, where one of the number $s$ is $\frac{-12}{3}$.
Let the other number be $x$.
$\therefore x+\frac{-12}{3}=\frac{-1}{3}$
$\Rightarrow x=\frac{-1}{3}-\frac{-12}{3}$
$\Rightarrow x=\frac{-1-(-12)}{3}=\frac{-1+12}{3}=\frac{11}{3}$
