Question

Alguém me ajuda nesta expressão:
$\frac{4}{3} + \frac{7}{5} \times ( \frac{1}{2} + \frac{4}{9}) - \frac{1}{5}$
​

Answer 1

Resposta:

$\frac{221}{90}$

Explicação passo a passo:

$\frac{4}{3} +\frac{7}{5} \ . \ (\frac{1}{2} +\frac{4}{9} )-\frac{1}{5} \\\\\frac{4}{3} +\frac{7}{5} \ . \ (\frac{9+(4 \ . \ 2)}{2 \ . \ 9} )\\\\\frac{4}{3} +\frac{7}{5} \ . \ (\frac{17}{18})-\frac{1}{5} \\\\\frac{4}{3} +\frac{119}{90} -\frac{1}{5} \\\\\frac{(4 \ . \ 3)}{3 \ . \ 30} +\frac{119}{5} \\\\\frac{239}{90} -\frac{1}{5} \\\\\frac{239-18}{18 \ . \ 5} \\\\\frac{221}{90}$
