Question

3/4.(4/5-7/3)-1/2 oi gente por favor vcs conseguem me ajudar

Answer 1

$\frac{3}{4}*(\frac{4}{5}-\frac{7}{3})-\frac{1}{2}=\frac{3}{4}*(\frac{12-35}{15})-\frac{1}{2}=\frac{3}{4}*(\frac{-23}{15})-\frac{1}{2}=\frac{-69}{60}-\frac{1}{2}=\\\\=\frac{-23}{20}-\frac{1}{2}=\frac{-23-10}{20}=-\frac{33}{20}$
