We want to find the point that best represents
[tex]\sqrt{5}[/tex]The square root of 5 is 2.236.
There are 4 points given on the number line:
A - 2
B - 2.1
C - 2.5
D - 3
When we approximate 2.236 to the nearest tenths, it yields 2.2
By observation, we see that 2.2 is closest to 2.1
And so, the answer is B - 2.1
