porfavor con las operaciones

Answer 1

$\frac{2}{3} + \frac{1}{6} - \frac{1}{9} \\ \\ \frac{6.2+3+2(-1)}{3^2.2} \\ \\ \frac{12+3-2}{3^2.2} \\ \\ \frac{13}{18} \\ \\ \\ ----------------- \\ \frac{5}{9} - \frac{7}{12} + \frac{11}{18} \\ \\ \frac{4.5+3(-7)+2.11}{3^2.2^2} \\ \\ \frac{20-3.7+22}{3^2.2^2} \\ \\ \frac{20-21+22}{3^2.2^2} \\ \\ \frac{7}{3^2^-^1.2^2} \\ \\ \frac{7}{12} \\ \\ \\ Saludos,Cordiales....!$
