| ① | Combine like terms |
| ② | Multiply $1$ by $ \dfrac{8}{9} $ to get $ \dfrac{8}{9} $. Write $ 1 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. $$ \begin{aligned} 1 \cdot \frac{8}{9} = \frac{1}{\color{red}{1}} \cdot \frac{8}{9} = \frac{8}{9} \end{aligned} $$ |
