1. $(\frac{1}{12}+ \frac{1}{6}):( \frac{3}{8}- \frac{1}{4})= (\frac{1}{12}+ \frac{2}{12}): (\frac{3}{8}- \frac{2}{8})= \frac{3}{12}: \frac{1}{8}= \frac{3}{12}* \frac{8}{1}= \frac{3}{3}* \frac{2}{1}= \frac{6}{3}$ = 2
2. $(1- \frac{4}{9}): (\frac{1}{3}- \frac{1}{4})= \frac{5}{9} :( \frac{4}{12}- \frac{3}{12})= \frac{5}{9}: \frac{1}{12}= \frac{5}{9} * \frac{12}{1}= \frac{60}{9}= \frac{20}{3}=6 \frac{2}{3}$
