start by writing all numbers like decimals
[tex]\begin{gathered} 3\frac{2}{3}=3.66666667 \\ \pi\cong3.1416 \\ \sqrt[]{3}=1.732 \end{gathered}[/tex]then using the decimals we can say that the least is square root 3 and the greatest is 3 2/3
The correct order should be
[tex]\sqrt[]{3};\bar{3.1};3.141;\pi;3\frac{2}{3}[/tex]
