$(-\frac{5}{6}-\frac{5}{6}ori0,36):\frac{17}{15}$

Answer 1

$\displaystyle \left(- \frac{5}{6} - \frac{5}{6} \cdot 0,36 \right): \frac{17}{15} = \left(- \frac{5}{6} - \frac{5}{6} \cdot \frac{36}{100} \right ): \frac{17}{15} =\left(- \frac{5}{6} - \frac{180}{600} \right ): \frac{17}{15} = \\ \\ =\left(- \frac{500}{600} - \frac{180}{600} \right): \frac{17}{15} =- \frac{680}{600} : \frac{17}{15} =- \frac{680}{600} \cdot \frac{15}{17} =- \frac{10200}{10200} =-1$
