Como foi?

ⓐ $- \frac{2}{3}$ is to the right of $−1$ on the number line.	$\begin{matrix} - \frac{2}{3}___−1 \\ - \frac{2}{3} > −1 \end{matrix}$
ⓑ $−3 \frac{1}{2}$ is to the right of $−3$ on the number line.	$\begin{matrix} −3 \frac{1}{2}___−3 \\ −3 \frac{1}{2} < −3 \end{matrix}$
ⓒ $- \frac{3}{4}$ is to the right of $- \frac{1}{4}$ on the number line.	$\begin{matrix} - \frac{3}{4}___- \frac{1}{4} \\ - \frac{3}{4} < - \frac{1}{4} \end{matrix}$
ⓓ $−2$ is to the right of $- \frac{8}{3}$ on the number line.	$\begin{matrix} −2___- \frac{8}{3} \\ −2 > - \frac{8}{3} \end{matrix}$
