Question

Проверьте,верно ли равенство? -102 : (-0,4) * (-0,2) + 73 = -4,4 -63/80 : 9/40 : (-1,75) -5,2

Answer 1

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