Question

8)calcule o valor de cada expressão
a)
b)
c)

Answer 1

a)

$\frac{2}{3} *\frac{3}{4} +\frac{1}{6} :\frac{5}{6} \\ \frac{1}{2} +\frac{1}{6} *\frac{6}{5} \\ \frac{1}{2} +\frac{1}{5}\\ \frac{7}{10}$

b)

$1:\frac{3}{2} +\frac{4}{9} *\frac{3}{6} \\ \frac{2}{3} +\frac{4}{9} *\frac{1}{2} \\ \frac{2}{3} +\frac{2}{9} \\ \frac{8}{9}$

c)

$\frac{5}{9} *\frac{6}{4} -\frac{4}{9} :\frac{10}{3} \\ \frac{5}{9}* \frac{3}{2}-\frac{4}{9} *\frac{3}{10}\\ \frac{5}{3} *\frac{1}{2}- \frac{2}{3} *\frac{1}{5} \\ \frac{5}{6} -\frac{2}{15} \\ \frac{7}{10}$
