5/17:(-45/34)
-3 3/5*2 7/9
-12/17:(-4)

Answer 1

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