$$ \begin{aligned}b\frac{d}{iweb+1}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{bd}{beiw+1}\end{aligned} $$ | |
① | Step 1: Write $ b $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} b \cdot \frac{d}{beiw+1} & \xlongequal{\text{Step 1}} \frac{b}{\color{red}{1}} \cdot \frac{d}{beiw+1} \xlongequal{\text{Step 2}} \frac{ b \cdot d }{ 1 \cdot \left( beiw+1 \right) } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ bd }{ beiw+1 } \end{aligned} $$ |
