| ① | Multiply $14$ by $ \dfrac{x}{26} $ to get $ \dfrac{ 14x }{ 26 } $. Step 1: Write $ 14 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 14 \cdot \frac{x}{26} & \xlongequal{\text{Step 1}} \frac{14}{\color{red}{1}} \cdot \frac{x}{26} \xlongequal{\text{Step 2}} \frac{ 14 \cdot x }{ 1 \cdot 26 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 14x }{ 26 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{14x}{26} $ by $ x $ to get $ \dfrac{ 14x^2 }{ 26 } $. Step 1: Write $ x $ as a fraction by putting $ \color{red}{ 1 } $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} \frac{14x}{26} \cdot x & \xlongequal{\text{Step 1}} \frac{14x}{26} \cdot \frac{x}{\color{red}{1}} \xlongequal{\text{Step 2}} \frac{ 14x \cdot x }{ 26 \cdot 1 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 14x^2 }{ 26 } \end{aligned} $$ |
