Answer 2

$1) - 9 \times \frac{4}{9} = - \frac{9 \times 4}{9} = - 4 \\ 2) \frac{5}{17} \div ( - \frac{45}{34})= - \frac{5 \times 34}{17 \times 45} = - \frac{2}{9}$
$- 3 \frac{3}{5} \times 2 \frac{7}{9} = - \frac{18 \times 25}{5 \times 9} = - 10 \\ - \frac{12}{17} \div ( - 4) = \frac{12}{17 \times 4} = \frac{3}{17}$
