-63/80 : 9/40 : (-1,75) -5,2 

Answer 1

$frac{-102:(-0.4)*(-0.2)+73}{- frac{63}{80}* frac{40}{9} : frac{7}{4}-5.2 } = frac{255*(-0.2)+73}{- frac{63}{18}* frac{4}{7}-5.2 }= frac{-51+73}{- frac{36}{18}-5.2 }= 22:(- frac{36}{5}) = -frac{110}{36}\ -frac{110}{36} = -3 frac{1}{18}$
$-3frac{1}{18} neq -4.4$
