| ① | Multiply $22$ by $ \dfrac{x}{6} $ to get $ \dfrac{ 22x }{ 6 } $. Step 1: Write $ 22 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 22 \cdot \frac{x}{6} & \xlongequal{\text{Step 1}} \frac{22}{\color{red}{1}} \cdot \frac{x}{6} \xlongequal{\text{Step 2}} \frac{ 22 \cdot x }{ 1 \cdot 6 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 22x }{ 6 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{22x}{6} $ by $ x $ to get $ \dfrac{ 22x^2 }{ 6 } $. 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. $$ \begin{aligned} \frac{22x}{6} \cdot x & \xlongequal{\text{Step 1}} \frac{22x}{6} \cdot \frac{x}{\color{red}{1}} \xlongequal{\text{Step 2}} \frac{ 22x \cdot x }{ 6 \cdot 1 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 22x^2 }{ 6 } \end{aligned} $$ |
