Question

O valor da expressão e

Answer 1

Resposta:

$\frac{7}{9} - \frac{ \frac{ \frac{2}{9} }{4} }{3 + \frac{5}{9} } \\ \frac{7}{9} - \frac{ \frac{2}{9} \times \frac{1}{4} }{ \frac{32}{9} } \\ \frac{7}{9} - \frac{ \frac{2}{36} }{ \frac{32}{9} } \\ \frac{7}{9} - \frac{2}{36} \times \frac{9}{32} \\ \frac{7}{9} - \frac{1}{18} \times \frac{9}{32} \\ \frac{7}{9} - \frac{9}{576} \\ mmc \: 576 \\ \\ \frac{448 - 9}{576} \\ \\ \frac{439}{576}$
