Quizplus · Accepted Answer

First, simplify the fractions before multiplying: $- \frac{42}{5} \cdot \frac{7}{21} \cdot \frac{1}{14} = - \frac{42}{5} \cdot \frac{1}{3} \cdot \frac{1}{14}$. Multiplying these together, $- \frac{42}{5} \cdot \frac{1}{3} \cdot \frac{1}{14} = - \frac{2}{5}$, which simplifies to $- \frac{1}{5}$ when considering the multiplication and division of the numbers involved.
