Answer 1

Resposta:

221/90

Explicação passo-a-passo:

$\frac{4}{3} +\frac{7}{5} .(\frac{1}{2} +\frac{4}{9}) -\frac{1}{5} =\\\frac{4}{3} +\frac{7}{5} .(\frac{17}{18}) -\frac{1}{5} =\\\frac{4}{3} +\frac{119}{90} -\frac{1}{5} =\\\frac{120+119-18}{90} =\\\frac{221}{90}$

Obs.:  → m.m.c de 2 e 9 = 18

         → m.m.c de 3, 90 e 5 = 90
