Question

me ajudem nessa questão

Answer 1

.dízima

$0,222...= \frac{2}{9} \\ \\ 0,888...= \frac{8}{9}$

logo
$\frac{2}{5} . \frac{2}{9} + \frac{3}{2} . \frac{8}{9} = \\ \\ \frac{4}{45} + \frac{24}{18} = \\ \\ mmc(45,18)=90 \\ \\ \frac{8+120}{90} = \frac{128}{90}$

simplificando

$\frac{128:2}{90:2} = \frac{64}{45}$
