Question

-7 1/3:2,75+1 2/19×(-19 3/14-(-9,6):7/15)

Answer 1

Ответ:

$- 7 \frac{1}{3} \div 2.75 + 1 \frac{2}{19} \times ( - 19 \frac{3}{14} - ( - 9.6) \div \frac{7}{15} ) = \\ = - \frac{22}{3} \times \frac{4}{11} + \frac{21}{19} ( \frac{ - 269}{14} + \frac{96}{10} \times \frac{15}{7} ) = \\ = - \frac{8}{3} + \frac{21}{19} \frac{ - 269 + 96 \times 3}{14} = \\ = - \frac{8}{3} + \frac{3}{19} \times \frac{19}{2} = \\ = - \frac{8}{3} + \frac{3}{2} = \\ = \frac{9-16}{6} = \frac{-7}{6}$
