① | Factor both the denominator and the numerator, then cancel the common factor. $\color{blue}{3t-2}$. $$ \begin{aligned} \frac{2-3t}{6t-4} & =\frac{ \left( -1 \right) \cdot \color{blue}{ \left( 3t-2 \right) }}{ 2 \cdot \color{blue}{ \left( 3t-2 \right) }} = \\[1ex] &= \frac{-1}{2} \end{aligned} $$ |
