| ① | Multiply $8$ by $ \dfrac{x^2}{12} $ to get $ \dfrac{ 8x^2 }{ 12 } $. Step 1: Write $ 8 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 8 \cdot \frac{x^2}{12} & \xlongequal{\text{Step 1}} \frac{8}{\color{red}{1}} \cdot \frac{x^2}{12} \xlongequal{\text{Step 2}} \frac{ 8 \cdot x^2 }{ 1 \cdot 12 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 8x^2 }{ 12 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{8x^2}{12} $ by $ x^4 $ to get $ \dfrac{ 8x^6 }{ 12 } $. Step 1: Write $ x^4 $ as a fraction by putting $ \color{red}{ 1 } $ in the denominator. Step 2: Multiply numerators and denominators.
