Question

The sum of two rational numbers is $\frac{-4}{3}$. If one of them is $-5$, find the other.

Answer 1

Let the required number be $x$.
Given condition $-5+x=\frac{-4}{3}$
$\Rightarrow x=\frac{-4}{3}+5$
$\Rightarrow x=\frac{-4+15}{5}$
$\therefore x=\frac{11}{3}$
Hence, the required number is $\frac{11}{3}$
