$\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\begin{array}{c|c} \bf { \underline{Given}} &\tt\red{What\:is\: rational\: number\:?}\end{array}} \\ \end{gathered}\end{gathered}\end{gathered} \end{gathered}\end{gathered} \end{gathered}$

$\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\begin{array}{cc} \bf { \underline{Answer}} \\ \tt\red{A \: number \: which \: can \: be \: written \: in \: the \: form} \\\tt\red{ \frac{P}{q} , where \: p \: and \: q \: are \: integers \: and \: q ≠ 0} \\ \tt \red{ is \: called \: a \: rational \: number.} \end{array}} \\ \end{gathered}\end{gathered}\end{gathered} \end{gathered}\end{gathered} \end{gathered}$

$\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\begin{array}{cc} \bf { \underline{For \: example}} \\ \\ \tt \red{ \frac{ - 2}{3} , \frac{6}{7}, \frac{9}{ - 5} \: are \: all \: rational \: numbers }\end{array}} \\ \end{gathered}\end{gathered}\end{gathered} \end{gathered}\end{gathered} \end{gathered}$

Since the numbers 0, -2, 4 can be written in the form $\frac{P}{q}$, they are also rational numbers.
