Dear student

\frac{- 2}{3} \times \frac{5}{7} + \frac{2}{9} \div \frac{1}{3} \times \frac{6}{7} = \frac{- 2}{3} \times \frac{5}{7} + \frac{2}{9} \times 3 \times \frac{6}{7} = \frac{- 10}{21} + \frac{2}{3} \times \frac{6}{7} = \frac{- 10}{21} + \frac{4}{7} = \frac{- 10 + 12}{21} = \frac{2}{21} So, reciprocal is \frac{21}{2}
