| ① | Multiply $16$ by $ \dfrac{x^2}{28x} $ to get $ \dfrac{ 16x^2 }{ 28x } $. Step 1: Write $ 16 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 16 \cdot \frac{x^2}{28x} & \xlongequal{\text{Step 1}} \frac{16}{\color{red}{1}} \cdot \frac{x^2}{28x} \xlongequal{\text{Step 2}} \frac{ 16 \cdot x^2 }{ 1 \cdot 28x } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 16x^2 }{ 28x } \end{aligned} $$ |
