Question

2/3-1/9+2/3 ajudem eu pfv​

Answer 1

Explicação passo-a-passo:

$\frac{2}{3} - \frac{1}{9} + \frac{2}{3} \\ = (\frac{2}{3} \times \frac{3}{3}) - \frac{1}{9} + (\frac{2}{3} \times \frac{3}{3} )\\ = \frac{2 \times 3}{3 \times 3} - \frac{1}{9} + \frac{2 \times 3}{3 \times 3} \\ \frac{6}{9} - \frac{1}{9} + \frac{6}{9} = \frac{11}{9}$
