| ① | Multiply $ \dfrac{284928}{1000001} $ by $ x $ to get $ \dfrac{ 284928x }{ 1000001 } $. 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. $$ \begin{aligned} \frac{284928}{1000001} \cdot x & \xlongequal{\text{Step 1}} \frac{284928}{1000001} \cdot \frac{x}{\color{red}{1}} \xlongequal{\text{Step 2}} \frac{ 284928 \cdot x }{ 1000001 \cdot 1 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 284928x }{ 1000001 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{310407}{1000001} $ by $ y $ to get $ \dfrac{ 310407y }{ 1000001 } $. Step 1: Write $ y $ as a fraction by putting $ \color{red}{ 1 } $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} \frac{310407}{1000001} \cdot y & \xlongequal{\text{Step 1}} \frac{310407}{1000001} \cdot \frac{y}{\color{red}{1}} \xlongequal{\text{Step 2}} \frac{ 310407 \cdot y }{ 1000001 \cdot 1 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 310407y }{ 1000001 } \end{aligned} $$ |
| ③ | Multiply $404666$ by $ \dfrac{z}{1000001} $ to get $ \dfrac{ 404666z }{ 1000001 } $. Step 1: Write $ 404666 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 404666 \cdot \frac{z}{1000001} & \xlongequal{\text{Step 1}} \frac{404666}{\color{red}{1}} \cdot \frac{z}{1000001} \xlongequal{\text{Step 2}} \frac{ 404666 \cdot z }{ 1 \cdot 1000001 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 404666z }{ 1000001 } \end{aligned} $$ |
