\frac{5}{6}

and

\frac{- 4}{3}

Associative property for addition:

(\frac{- 7}{9} + \frac{5}{6}) + (\frac{- 4}{3})

\(=\)

\frac{i}{i}

\frac{- 7}{9} + (\frac{- 4}{3} + \frac{5}{6})

\(=\)

\frac{i}{i}

Associative property for multiplication:

(\frac{- 7}{9} \times \frac{5}{6}) \times (\frac{- 4}{3})

\(=\)

\frac{i}{i}

(\frac{- 7}{9}) \times (\frac{5}{6} \times \frac{- 4}{3})

\(=\)

\frac{i}{i}
