oder the following from least to greatest

You simply have to translate every number into its (approximated) decimal expansion:
[tex]\begin{array}{cc}\text{num}&\text{exp}\\\sqrt{11}&3.316\\-0.4&-0.4\\-\frac{4}{3}&-1.33\\0.8&0.8\\\sqrt{2}&1.4142\end{array}[/tex]
So, the numbers lay in this order:
[tex]\begin{array}{cc}\text{num}&\text{exp}\\-\frac{4}{3}&-1.33\\-0.4&-0.4\\0.8&0.8\\\sqrt{2}&1.4142\\\sqrt{11}&3.316\end{array}[/tex]
