To order these from least to greatest it's easiest to turn them all into decimals first then arrange them all in the order of least to greatest like this.
[tex] -\sqrt{4} =-2[/tex]
[tex]3.5[/tex]
[tex] \sqrt{11}=3.31662479036 [/tex]
[tex]11/20=.55, 3.55[/tex]
Now arrange
-2, 3.31662479036, 3.5, 3.55
Hope this helps!=)
