Question:
What number should be subtracted from $\frac{-5}{3}$ to get $\frac{5}{6}$ ?
Solution:
Let $x$ be subtracted.
$\therefore \frac{-5}{3}-x=\frac{5}{6}$
$\Rightarrow x=\frac{-5}{3}-\frac{5}{6}$
$\Rightarrow x=\frac{-10}{6}-\frac{5}{6}$
$\Rightarrow x=\frac{-10-5}{6}=\frac{-15}{6}=\frac{-5}{2}$
