[tex]( \frac{16}{100} + \frac{16}{99} ) \div \frac{28}{100} \div \frac{2}{99 }{} - \frac{6}{7} = ( \frac{4}{25} + \frac{16}{99} ) \div \frac{7}{25} \div \frac{2}{99} - \frac{6}{7} = \frac{396 + 400}{2475} \div \frac{7}{25} \div \frac{2}{99} - \frac{6}{7} = \frac{796}{2475} \times \frac{25}{7} \times \frac{99}{2} - \frac{6}{7} = \frac{796}{99} \times \frac{1}{7} \times \frac{99}{2} - \frac{6}{7} = \frac{398}{7} - \frac{6}{7} = \frac{392}{7} = 56[/tex]
