How does one get from . $\frac{4\sqrt{3}}{6}\,\text{ to }\,\frac{2}{\sqrt{3}}$ ?
Multiply by $\frac{\sqrt{3}}{\sqrt{3}}$

. . $\frac{4\sqrt{3}}{6}\cdot{\color{blue}\frac{\sqrt{3 }}{\sqrt{3}}} \;=\;\frac{4\cdot\sqrt{3}\cdot\sqrt{3}}{6\cdot\sqr t{3}} \;=\; \frac{4\cdot3}{6\sqrt{3}} \;=\;\frac{12}{6\sqrt{3}} \;=\;\frac{2}{\sqrt{3}}$
