| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{48}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ \sqrt{5} } \cdot \sqrt{48} = 4 \sqrt{15} $$ Simplify denominator. $$ \color{blue}{ \sqrt{48} } \cdot \sqrt{48} = 48 $$ |
| ③ | Divide both numerator and denominator by 4. |
