Question

Galerinha me ajuda ai novamente com o calculo desta questão por favor ?

Answer 1

a)
$(\frac{1}{2}+\frac{1}{3}) \div \frac{5}{3}=(\frac{3+2}{6}) \div \frac{5}{3}=\frac{5}{6}\div\frac{5}{3}=\\ \\ \frac{5}{6}*\frac{3}{5}=\frac{3}{6}=\frac{1}{2}$

b)
$x=\frac{1}{3}*(\frac{2}{3}\div \frac{1}{7})=\frac{1}{3}*\frac{2}{3}*\frac{7}{1}=\frac{14}{9}$

c)
$(\frac{1}{2}+\frac{3}{2})^2 \div\frac{1}{4}*\frac{1}{2}=4*4*\frac{1}{2}=8$
