Answer 1

$-1- \frac{5}{9}* 1=- \frac{9}{9} - \frac{5}{9} =- \frac{14}{9} =-1 \frac{5}{9}$
$-1- \frac{5}{9} * \frac{3}{5} =-1- \frac{1}{3} * \frac{1}{1} =-1 \frac{1}{3}$
$-0,45= -\frac{45}{100} =- \frac{9}{20}$
$-1- \frac{5}{9} * (-\frac{9}{20} )=-1- \frac{1}{1} * (-\frac{1}{4} )=-1+ \frac{1}{4} =-\frac{3}{4}$
