como faso essa conta, resposta

Answer 1

$\frac{17}{3}-\left[\frac{3}{4} \div \frac{1}{6}+\left(\frac{3}{10} \div \frac{9}{5}\right)\right]=\\ \\ \frac{17}{3}-\left[\frac{3}{4} * \frac{6}{1}+\left(\frac{3}{10} * \frac{5}{9}\right)\right]=\\ \\ \frac{17}{3}-\left[\frac{9}{2}+\frac{1}{6}\right]=\\ \\ \frac{17}{3}-\frac{9}{2}-\frac{1}{6}=\\ \\ \frac{34-27-2}{12}=\frac{5}{12}$
