Two possible rational numbers between $-\frac{2}{3}$ and $\frac{1}{2}$ are

Explanation

In order to determine two possible number between $-\frac{2}{3}$ and $\frac{1}{2}$ have to draw number line- $-\frac{2}{3} \rightarrow -\frac{4}{6}$ $\frac{1}{2} \rightarrow \frac{3}{6}$ <table> <tr> <td>$-\frac{4}{6}$</td> <td>$-\frac{3}{6}$</td> <td>$-\frac{2}{6}$</td> <td>$-\frac{1}{6}$</td> <td>0</td> <td>$\frac{1}{6}$</td> <td>$\frac{2}{6}$</td> <td>$\frac{3}{6}$</td> </tr> </table> There are the possible rational numbers between, $-\frac{2}{3}$ and $\frac{1}{2}$ Hence option (b) will be the right answer.
