Calculate:
- $$\dfrac{5}{9}\cdot\dfrac{-4}{8}$$
- $$\dfrac{-3}{7}\cdot\dfrac{-1}{10}$$
See development and solution
Development:
- $$\dfrac{5}{9}\cdot\dfrac{-4}{8}=\dfrac{5}{9}\cdot\dfrac{-1}{2}=\dfrac{5\cdot(-1)}{9\cdot2}=\dfrac{-5}{18}$$
- $$\dfrac{-3}{7}\cdot\dfrac{-1}{10}=\dfrac{-3\cdot(-1)}{7\cdot10}=\dfrac{3}{70}$$
Solution:
- $$\dfrac{-5}{18}$$
- $$\dfrac{3}{70}$$
