| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{12}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 5 } \cdot \sqrt{12} = 10 \sqrt{3} $$ Simplify denominator. $$ \color{blue}{ 3 \sqrt{12} } \cdot \sqrt{12} = 36 $$ |
| ③ | Divide numerator and denominator by $ \color{blue}{ 2 } $. |
