Work Step by Step
Some of the numbers will be approximated to one decimal point $(\sqrt{10} ).$
Organize your real number line so all integers are set to be an equal distance apart.
If you set this distance to be 1cm, you can measure the 0.1 increments with millimeters.
Graph the integers first, $(0, -1).$
$-0.4 \quad $ is between $-1$ and $0$ ($4$ mm left of $0$)
$\displaystyle \frac{3}{2}=1.5 \quad $ is between $1$ and $2$ ($5$ mm right of $1$)
$\sqrt{10}\approx 3.2\quad $ is between $3 $ and $4 $ ($2$ mm right of $3$)
