Verify the associative property for addition and multiplication for the rational numbers

$\frac{- 7}{9}$ ,

$\frac{5}{6}$ 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:

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

$=$

$\frac{i}{i}$

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

$=$

$\frac{i}{i}$
