Soluciona:
- $\dfrac{6}{7}:\Big(-\dfrac{5}{11}\Big)$
- $\dfrac{-9}{10}:\Big(-\dfrac{2}{5}\Big)$
- $\dfrac{6}{7}:\Big(-\dfrac{5}{11}\Big)=\dfrac{6}{7}\cdot\Big(-\dfrac{11}{5}\Big)=\dfrac{6\cdot(-11)}{7\cdot5}=\dfrac{-66}{35}.$
- $\dfrac{-9}{10}:\Big(-\dfrac{2}{5}\Big)=\dfrac{-9}{10}\cdot\Big(-\dfrac{5}{2}\Big)=\dfrac{(-9)\cdot(-5)}{10\cdot2}=\dfrac{45}{20}=\dfrac{9}{4}.$
- $\dfrac{-66}{35}$
- $\dfrac{9}{4}$
