3/2 - [-12-(1/3-3/5)-(-5+6/4)]-(- 1/2) Como faso essa conta ?

Answer 1

$\frac{3}{2}-[-12-( \frac{1}{3}- \frac{3}{5})-(-5+ \frac{6}{4})]-(- \frac{1}{2})=$

$\frac{3}{2}-[-12-( \frac{5-9}{15})[tex]-(- \frac{14}{4})+ \frac{1}{2}=$

$\frac{3}{2}-[-12-(- \frac{4}{15})+ \frac{7}{2}+ \frac{1}{2}=$

$\frac{3}{2}-[-12+ \frac{4}{15}+ \frac{7}{2}]+ \frac{1}{2}=$

$\frac{3}{2}+12- \frac{4}{15}- \frac{7}{2}+ \frac{1}{2}=$

$\frac{3}{2}+ \frac{12}{1}- \frac{4}{15}- \frac{6}{2}=$
mmc(2,15) = 30

$\frac{45+360-8-90}{30}= \frac{307}{30}$=$10 \frac{7}{30}$
