| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{150}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 10 \sqrt{6} } \cdot \sqrt{150} = 300 $$ Simplify denominator. $$ \color{blue}{ \sqrt{150} } \cdot \sqrt{150} = 150 $$ |
| ③ | Divide both the top and bottom numbers by $ \color{orangered}{ 150 } $. |
| ④ | Remove 1 from denominator. |
