Answer:
The distance is [tex]\frac{3}{10} = 0.3[/tex]
Step-by-step explanation:
First notice that [tex]\sqrt {\frac{25}{4} }=\frac{5}{2}[/tex]
Then we need the distance between those two fractions, which can be found via the absolute value of the difference between these two numbers;
[tex]distance=|\frac{11}{5} -\frac{5}{2} |\\distance=|\frac{22}{10} -\frac{25}{10} |\\distance= \-\frac{3}{10} |\\distance= 0.3[/tex]
