| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{3}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 20 \sqrt{3} } \cdot \sqrt{3} = 60 $$ Simplify denominator. $$ \color{blue}{ 40 \sqrt{3} } \cdot \sqrt{3} = 120 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 60 } $. |
