Answer 1

Dear Student,

​​​​​$$\begin{gathered} \mathrm{Let}\mathrm{x}\mathrm{be}\mathrm{the}\mathrm{required}\mathrm{rational}\mathrm{number}. \\ \mathrm{Now},\mathrm{according}\mathrm{to}\mathrm{question}: \\ \mathrm{x}=-\mathrm{x} \\ \Rightarrow \mathrm{x}+\mathrm{x}=0 \\ \Rightarrow 2\mathrm{x}=0 \\ \Rightarrow \mathrm{x}=\frac{0}{2}=0 \end{gathered}$$

So, the rational number that is equal to its negative is 0.
