Answer 1

Respuesta:

$\bold{ - \frac{1161}{100} }$

Explicación paso a paso:

$\bold{\frac{1}{5} ( 1 + \frac{3}{5} - \frac{9}{10} ) + [ 2 + 5 ( \frac{2}{8} - 3 ) ]}$

$\bold{\frac{1}{5} ( \frac{1}{1} + \frac{3}{5} - \frac{9}{10} ) + [ 2 + 5 ( \frac{2}{8} - \frac{3}{1} ) ]}$

$\bold{\frac{1}{5} ( \frac{1(10)}{1(10)} + \frac{3(2)}{5(2)} - \frac{9}{10} ) + [ 2 + 5 ( \frac{2}{8} - \frac{3(8)}{1(8)} ) ]}$

$\bold{\frac{1}{5} ( \frac{10}{10} + \frac{6}{10} - \frac{9}{10} ) + [ 2 + 5 ( \frac{2}{8} - \frac{24}{8} ) ]}$

$\bold{\frac{1}{5} ( \frac{10 + 6 - 9}{10} ) + [ 2 + 5 ( \frac{2 - 24}{8} ) ]}$

$\bold{\frac{1}{5} ( \frac{7}{10} ) + [ 2 + 5 ( \frac{- 22}{8} ) ]}$

$\bold{\frac{1(7)}{5(10)} + [ 2 + 5 ( \frac{- 11}{4} ) ]}$

$\bold{\frac{7}{50} + [ 2 - \frac{ 55}{4} ]}$

$\bold{\frac{7}{50} + [ \frac{2}{1} - \frac{ 55}{4} ]}$

$\bold{\frac{7(2)}{50(2)} + [ \frac{2(100)}{1(100)} - \frac{ 55(25)}{4(25)} ]}$

$\bold{\frac{14}{100} + [ \frac{200}{100} - \frac{1375}{100} ]}$

$\bold{\frac{14 + 200 - 1375}{100}}$

$\bold{ - \frac{1161}{100} }$
