#### Answer

$-\frac{60}{11}, -3, \sqrt {11}, 5.5, \sqrt {31}$

#### Work Step by Step

Restate each number as a decimal to compare.
$-3\ \ =-3$
$\sqrt {31}=\ \ \ 5.568$
$\sqrt {11}=\ \ \ 3.317$
$5.5\ \ = \ \,\ \ \ 5.5$
$-\frac{60}{11}=\ \ \ \ -5.455$
Reorder from least to greatest.
$-\frac{60}{11}=\ \ \ \ -5.455$
$-3\ \ =-3$
$\sqrt {11}=\ \ \ 3.317$
$5.5\ \ = \ \,\ \ \ 5.50$
$\sqrt {31}=\ \ \ 5.568$
