Hello!
The answer is: D. is the fourth picture.
Why?
First, we need to make these numbers entire or decimal numbers, in order to see where are they located:
[tex]2\sqrt{5} =4.47\\\frac{6}{7}*\pi =2.69\\\sqrt{16} =4[/tex]
So, we should look for the image that shows the following order it: 2.69, 4 and 4.47
or
[tex]\frac{6}{7} *\pi[/tex]
[tex]\sqrt{16} =4[/tex]
[tex]2\sqrt{5}[/tex]
Then, we just need to find the image where they are properly located/ordered:
So, the correct image is D. is the fourth picture.
Have a nice day!
