Answer 2

$\frac{617}{315}$

Explicación paso a paso:

$\frac{4}{5} \div \frac{7}{8} - \frac{2}{3} \times \frac{5}{6} + \frac{8}{5} = \\ \\ \frac{4}{5} \times (\frac{8}{7} ) - \frac{2}{3} \times ( \frac{5}{6} ) + \frac{8}{5} = \\ \\ \frac{4 \times 8}{5 \times 7} - \frac{2}{3} \times ( \frac{5}{6} ) + \frac{8}{5} = \\ \\ \frac{32}{35} - \frac{2}{3} \times ( \frac{5}{6} ) + \frac{8}{5} = \\ \\ \frac{32}{35} - \frac{2 \times 5}{3 \times 6} + \frac{8}{5} = \\ \\ \frac{32}{35} - \frac{10}{18} + \frac{8}{5} = \\ \\ \frac{32}{35} - \frac{5}{9} + \frac{8}{5} = \\ \\ \frac{288}{315} - \frac{175}{315} + \frac{8}{5} = \\ \\ \frac{288 - 175}{315} + \frac{8}{5} = \\ \\ \frac{11 3}{315} + \frac{8}{5} = \\ \\ \frac{113}{315} + \frac{504}{315} = \\ \\ \frac{113 + 504}{315} = \\ \\ \frac{617}{315}$
