Question

a. [$\frac{5}{3} [\frac{1}{2} +(- \frac{3}{4}/2)]$
b. $1/ \frac{2}{3} - \frac{3}{4} /3+5/ \frac{1}{5}$
Não estou conseguindo resolver

Answer 1

a.
$\frac{5}{3} [ \frac{1}{2} +( -\frac{3}{4}/2 )]=\frac{5}{3} [ \frac{1}{2} +(- \frac{3}{8} )]= \frac{5}{3}. [ \frac{1}{8} ]= \frac{5}{24}$
b.
$1/ -\frac{1}{12} /8/ \frac{1}{5} = \frac{1}{1} . -\frac{12}{1} / \frac{8}{1} . \frac{5}{1} = -\frac{12}{1} / \frac{40}{1} = -\frac{12}{40} =- \frac{3}{10}$
