Question

simplifique a expressão.
$\frac{ \frac{3}{4} -0,005}{ \frac{4}{5}-1 }$

Answer 1

$\frac{ \frac{3}{4} - \frac{5}{1000} }{ \frac{4}{5} - 1 } \\ \\ \frac{ \frac{750}{1000} - \frac{5}{1000} }{ \frac{4}{5} - \frac{5}{5} } \\ \\ \frac{ \frac{745}{1000} }{ - \frac{1}{5} } \\ \\ \frac{750}{100} \times ( - 5) \ \\ \ \\ - \frac{750}{20} = - \frac{75}{2} = -37.5$
