| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{12}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{75} } \cdot \sqrt{12} = 30 $$ Simplify denominator. $$ \color{blue}{ \sqrt{12} } \cdot \sqrt{12} = 12 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 6 } $. |
