Question

What number should be suvtracted from $\frac{-5}{3}$ to get $\frac{5}{6}?$

Answer 1

Let x be the number that should be subtracted from $\frac{-5}{3}\mathrm{to}\mathrm{get}\frac{5}{6}.$
Then, according to the question, we have
$$\begin{gathered} \frac{-5}{3}-x=\frac{5}{6} \\ \Rightarrow x=\frac{-5}{3}-\frac{5}{6}=\frac{-5\times 2}{3\times 2}-\frac{5}{6}=\frac{-10-5}{6}=\frac{-15}{6}=\frac{-5}{2} \end{gathered}$$
