Answer 1

Ответ:

$\frac{3.75 + 4}{ {3.75}^{2} + 16 } \times ( \frac{3.75 + 4}{3.75 - 4} + \frac{3.75 - 4}{3.75 + 4} ) = - 10 \frac{11}{47}$

$\frac{7.75}{23.5} \times (\frac{7.75}{ - 0.25} + \frac{ - 0.25}{7.75} )$

$\frac{7.75}{23.5} \times \frac{31}{4 } - \frac{1}{4} + ( - \frac{1}{4} ) \div \frac{31}{4}$

$\frac{7.75}{23.5} \times ( \frac{31}{ - 1} + \frac{ - 1}{31})$

$\frac{7.75}{23.5} \times ( - 31 + \frac{ - 1}{31} )$

$\frac{ - 31}{94} \times \frac{962}{31} = - \frac{1}{47} \times 481 = - \frac{481}{47} = - 10 \frac{11}{47}$
