Quizplus · Accepted Answer

To solve this problem, we simply multiply the fraction $\frac { 13 } { 9 }$ by the fraction $-\frac { 54 } { 13 }$. When we multiply fractions, we multiply the numerators together and we multiply the denominators together. Therefore, we have: $$\frac { 13 } { 9 } \left(-\frac { 54 } { 13 }\right) = \frac{13 \cdot (-54)}{9 \cdot 13}$$ We can simplify this by canceling the common factor of 13: $$\frac{13 \cdot (-54)}{9 \cdot 13} = \frac{(-6) \cdot (3 \cdot 13)}{3 \cdot 3 \cdot 13} = \frac{-6}{3} = -2 \cdot 3 = -6$$ Therefore, the answer is B) $-6$.
