Explanation
| $$ \begin{aligned}\frac{2}{3}\cdot\frac{3}{4}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{1}{2}\end{aligned} $$ | |
| ① | Multiply $ \dfrac{2}{3} $ by $ \dfrac{3}{4} $ to get $ \dfrac{1}{2} $. Cancel $ \color{red}{ 3 } $ in first and second fraction. Step 2: Multiply numerators and denominators. Step 3: Cancel down by $ \color{blue}{2} $ $$ \begin{aligned} \frac{2}{3} \cdot \frac{3}{4} & = \frac{2}{\color{red}{1}} \cdot \frac{\color{red}{1}}{4} = \frac{2 : \color{blue}{2}}{4 : \color{blue}{2}} = \\[1ex] &= \frac{1}{2} \end{aligned} $$ |
