1)

$\frac{(\frac{69}{10}+\frac{51}{20})*\frac{13}{5} -\frac{35}{10}*\frac{27}{10}}{\frac{73}{9}-(\frac{25}{12}-\frac{19}{18}):\frac{37}{4}}=\frac{\frac{138}{20}*\frac{13}{5}-\frac{945}{100}}{\frac{73}{9}-(\frac{37}{36}*\frac{4}{37}) } =\frac{\frac{414-945}{100} }{\frac{73}{9}-\frac{1}{9} }=\frac{-\frac{531}{100} }{8} =-\frac{531}{100}*\frac{1}{8} =-\frac{531}{800}$

2)

$\frac{\frac{7}{25}+\frac{1}{3}*\frac{24}{5}-\frac{22}{25}}{(\frac{45}{10}+\frac{2}{5}):\frac{7}{20}}=\frac{\frac{7}{25}+\frac{8}{5}-\frac{22}{25}}{\frac{49}{10}*\frac{20}{7} }=\frac{\frac{25}{25} }{14}=\frac{1}{14}$
