Answer 2

Answer

$\frac{53}{10} - ( \frac{9}{2} - ( \frac{7}{6} - ( \frac{2}{5} + \frac{7}{10} - \frac{4}{15} ))) \\ \\ = \frac{53}{10} - ( \frac{9}{2} - ( \frac{7}{6} - ( \frac{12+ 21 - 8}{30} ))) \\ \\ = \frac{53}{10} - ( \frac{9}{2} - ( \frac{7}{6} - \frac{25}{30} )) \\ \\ = \frac{53}{10} - ( \frac{9}{2} - (\frac{35-25}{30})) \\ \\ = \frac{53}{10} - ( \frac{9}{2} + \frac{10}{30} ) \\ \\ = \frac{53}{10} - \frac{135-10}{30} \\ \\ = \frac{53}{10} - \frac{125}{30} \\ \\ = \frac{159-125}{30} \\ \\ = \frac{34}{30} \\ \\ = \frac{17}{15}$
