Question

me ajudem meu Deus porfavor ​

Answer 1

a) $\sf = \frac{5}{9} + \frac{1}{3} \times \frac{2}{3}$

$\sf = \frac{5}{9} + \frac{1 \times 2}{3 \times 3}$

$\sf = \frac{5}{9} + \frac{2}{9}$

$\sf \color{blue}{ = \frac{7}{9} }$

.

b)$\sf = ( \frac{5}{9} + \frac{1}{3} ) \times \frac{2}{3}$

$\sf = ( \frac{5}{9} + \frac{1 \times 3}{3 \times 3} ) \times \frac{2}{3}$

$\sf = \frac{8}{9} \times \frac{2}{3}$

$\sf = \frac{8 \times 2}{9 \times 3}$

$\sf \color{blue}{ = \frac{16}{27} }$
