resolva a fração a seguir:

Answer 1

Resposta:

$\frac{111}{36}$

Explicação passo-a-passo:

$3.\frac{9}{4} - {{[(\frac{2}{3})^{2} + 2] : \sqrt{\frac{4}{9}}=> \frac{27}{4} - {{[\frac{4}{9}^{} + 2] : \frac{2}{3} => \frac{27}{4} - {{[\frac{4+ 2.9}{9} ] : \frac{2}{3} => \frac{27}{4} - {{[\frac{4+ 18}{9} ] : \frac{2}{3} =>$

$\frac{27}{4} - {{\frac{22}{9} : \frac{2}{3} => \frac{27}{4} - {{\frac{22}{9} . \frac{3}{2}=> \frac{27}{4} - {{\frac{66}{18} => => \frac{27.9 -66.2}{36} => \frac{243 - 132}{36} => \frac{111}{36}$
