[tex] \frac{7}{8} \times \frac{5}{9} \div ( \frac{4}{9} - (\frac{1}{6} ) {}^{2} + \frac{2}{3} ) = [/tex]
[tex] = \frac{45}{72} \div ( \frac{4}{9} - \frac{1}{36} + \frac{2}{3} ) = [/tex]
[tex] = \frac{5}{8} \div ( \frac{16}{36} - \frac{1}{36} + \frac{24}{36} )[/tex]
[tex] = \frac{ 5}{8} \div \frac{39}{36} [/tex]
[tex] = \frac{5}{8} \times \frac{36}{39} [/tex]
[tex] = \frac{5}{8} \times \frac{12}{13} [/tex]
[tex] = \frac{5}{2} \times \frac{3}{13} [/tex]
