$$z\cdot\dfrac{1}{3}=\dfrac{z}{3}$$
Explanation
| $$ \begin{aligned}z\cdot\frac{1}{3}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{z}{3}\end{aligned} $$ | |
| ① | Multiply $z$ by $ \dfrac{1}{3} $ to get $ \dfrac{ z }{ 3 } $. Step 1: Write $ z $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} z \cdot \frac{1}{3} & \xlongequal{\text{Step 1}} \frac{z}{\color{red}{1}} \cdot \frac{1}{3} \xlongequal{\text{Step 2}} \frac{ z \cdot 1 }{ 1 \cdot 3 } \xlongequal{\text{Step 3}} \frac{ z }{ 3 } \end{aligned} $$ |
