Answer :

The numbers are:

[tex]\frac{18}{3}[/tex][tex]\sqrt[]{15}[/tex][tex]\frac{9}{2}[/tex][tex]3.2[/tex][tex]\sqrt[]{27}[/tex]

First number is:

6

Second number is:

3^2 = 9

4^2 = 16

So, Square Root of 15 is really close to 4, but less.

Third Number is:

4.5

Fourth Number is:

3.2

Fifth Number is:

5^2 = 25

6^2 = 36

So, square root of 27 is close to 5, but greater.

Least to Greatest:

[tex]3.2,\sqrt[]{15},\frac{9}{2},\sqrt[]{27},\frac{18}{3}[/tex]
