Answer 1

1)
$\frac{18}{27} - ( \frac{3}{29} + ( \frac{7}{29} - \frac{4}{29} )) = \frac{18}{29} - ( \frac{3}{29} + \frac{3}{29} ) = \frac{18}{29} - \frac{6}{29} = \frac{12}{29}$
2)
$\frac{19}{27} - ( \frac{6}{27} + ( \frac{10}{27} - \frac{7}{27} )) = \frac{19}{27} - ( \frac{6}{27} + \frac{3}{27}) = \frac{19}{27} - \frac{9}{27} = \frac{10}{27}$
