Ответ:

$1) \frac{4}{9} - ( - \frac {1}{6} ) = \frac{4}{9} + \frac{1}{6} = \frac{8 + 3}{18} = \frac{11}{18}$

$2) - \frac{5}{8} - ( - \frac{7}{10}) = - \frac{5}{8} + \frac{7}{10} = \frac{ - 25 + 28}{40} = \frac{3}{40} = 0.075$

$3)\frac{7}{12} - \frac{17}{18} = \frac{21 - 34}{36} = - \frac{13}{36}$

$4) - \frac{9}{20} - \frac{4}{15} = - \frac{27 + 16}{60} = - \frac{43}{60}$

$5) \frac{3} {10} - \frac{8}{15} = \frac{9 - 16}{30} = - \frac{7}{30}$

$6) - \frac{11}{25} - ( - \frac{3}{10} ) = - \frac{11}{25} + \frac{3}{10} = \frac{ - 22 + 15}{50} = - \frac{7}{50} = - 0.14$
