$1)( \frac{1}{3} - \frac{5}{8} ) \times ( - \frac{6}{7} ) = - \frac{7}{24} \times ( - \frac{6}{7} ) = \frac{1}{4}$

$2)( - \frac{5}{12} - \frac{7}{30} ) \div \frac{13}{15} = - \frac{13}{15} \times \frac{15}{13} = - \frac{1}{4} \times 3 = - \frac{3}{4}$

$3)( - \frac{3}{4} - \frac{1}{6} ) \div ( - 1 \frac{3}{8} ) = - \frac{11}{12} \div ( - \frac{11}{8} ) = \frac{11}{12} \times \frac{8}{11} = \frac{1}{3} \times 2 = \frac{2}{3}$

$4)( \frac{1}{4} - \frac{5}{18} ) \times 36 = - \frac{1}{36} \times 36 = - 1$
