| ① | Multiply $9$ by $ \dfrac{x^2}{6} $ to get $ \dfrac{ 9x^2 }{ 6 } $. Step 1: Write $ 9 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 9 \cdot \frac{x^2}{6} & \xlongequal{\text{Step 1}} \frac{9}{\color{red}{1}} \cdot \frac{x^2}{6} \xlongequal{\text{Step 2}} \frac{ 9 \cdot x^2 }{ 1 \cdot 6 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 9x^2 }{ 6 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{9x^2}{6} $ by $ x^3 $ to get $ \dfrac{ 9x^5 }{ 6 } $. Step 1: Write $ x^3 $ as a fraction by putting $ \color{red}{ 1 } $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} \frac{9x^2}{6} \cdot x^3 & \xlongequal{\text{Step 1}} \frac{9x^2}{6} \cdot \frac{x^3}{\color{red}{1}} \xlongequal{\text{Step 2}} \frac{ 9x^2 \cdot x^3 }{ 6 \cdot 1 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 9x^5 }{ 6 } \end{aligned} $$ |
