-7/18*(- 24/35)

9/20: (27/55)

Answer 1

- 7/18*(-24/35)
1)-24/35= -0,685
2) - 7/18= - 0,388
3) -0,685*-0,388=0,26578
9/20(27/55)=22,09

Answer 2

$- frac{7}{18} * (-frac{24}{35}) = frac{1}{3} * frac{4}{5} = frac{4}{15}$
$frac{9}{20}: frac{27}{55} = frac{9}{20}* frac{55}{27} = frac{1}{4}*frac{11}{3}= frac{11}{12}$
