Question

$- 10 \frac{4}{5} \div (1 \ \div \frac{10}{17} ) =$

Answer 1

$-10\frac{4}{5}\div (1\div \frac{10}{17})=-\frac{54}{5}:\frac{17}{10}=-\frac{54}{5}\cdot \frac{10}{17}=-\frac{54\cdot 2}{17}=-\frac{108}{17}=-6\frac{6}{7}$

$-10\frac{4}{5}:1\frac{10}{17}=-\frac{54}{5}:\frac{27}{17}=-\frac{54\cdot 17}{5\cdot 27}=-\frac{2\cdot 17}{5}=-\frac{34}{5}=-6,8$
