SOLUTION
The given expression is:
[tex]\frac{2\sqrt{5}}{\sqrt{15}}[/tex]
This is simplified as follows:
[tex]\begin{gathered} \frac{2\sqrt{5}}{\sqrt{15}}\times\frac{\sqrt{15}}{\sqrt{15}} \\ =\frac{2\sqrt{75}}{15} \\ =\frac{10\sqrt{3}}{15} \\ =\frac{2\sqrt{3}}{3} \end{gathered}[/tex]
Therefore the required answer is:
[tex]\frac{2\sqrt{3}}{3}[/tex]
