$\bold{= > - \frac{2}{3} \times \frac{5}{7} + \frac{2}{9} \div \frac{1}{3} + \frac{6}{7}}$

$\bold{= > - \frac{ 10}{21} + \frac{2}{9} \times 3 + \frac{6}{7}}$

$\bold{= > - \frac{10}{21} + \frac{2}{3} + \frac{6}{7}}$

=>L.C.M OF 21,3&7 IS 21

$\bold{= > \frac{ - 10 + 2×7 + 6×3}{21}}$

$\bold{= > \frac{ - 10 + 14 + 18}{21}}$

$\bold{\red{= > \frac{22}{21} }}$

=>22/21 is your answer after simplification
