Explanation
| $$ \begin{aligned}18x \cdot \frac{y^2}{12xy^3}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{18xy^2}{12xy^3}\end{aligned} $$ | |
| ① | Multiply $18x$ by $ \dfrac{y^2}{12xy^3} $ to get $ \dfrac{ 18xy^2 }{ 12xy^3 } $. Step 1: Write $ 18x $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 18x \cdot \frac{y^2}{12xy^3} & \xlongequal{\text{Step 1}} \frac{18x}{\color{red}{1}} \cdot \frac{y^2}{12xy^3} \xlongequal{\text{Step 2}} \frac{ 18x \cdot y^2 }{ 1 \cdot 12xy^3 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 18xy^2 }{ 12xy^3 } \end{aligned} $$ |
