$(6 frac{1}{8} - 1frac{75}{100} ) : ( 9 - 2frac{2}{10} * ( 5frac{6}{11} - 3 frac{5}{10} )) * 1frac{2}{7} =$

Answer 1

$(6 frac{1}{8} - 1frac{75}{100} ) : ( 9 - 2frac{2}{10} * ( 5frac{6}{11} - 3 frac{5}{10} )) * 1frac{2}{7} = \ (5 frac{1}{8} - frac{75}{100} ) : ( 9 - 2frac{1}{5} * ( 2frac{6}{11} - frac{5}{10} )) * frac{9}{7} = \ ( frac{41}{8} - frac{3}{4} ) : ( 9 - frac{11}{5} * ( frac{28}{11} - frac{1}{2} )) * frac{9}{7} = ( frac{41}{8} - frac{6}{8} ) : ( 9 - frac{11}{5} * ( frac{56}{22} - frac{11}{22} )) * frac{9}{7} =$
$= frac{35}{8} : ( 9 - frac{11}{5} * frac{45}{22}) * frac{9}{7} =frac{35}{8} : ( 9 - frac{9}{2}) * frac{9}{7} =frac{35}{8} : ( frac{18}{2} - frac{9}{2}) * frac{9}{7} = \ =frac{35}{8} : frac{9}{2} * frac{9}{7} =frac{35}{8} * frac{2}{9} * frac{9}{7}=frac{35}{4} * frac{1}{7}= frac{5}{4} =1 frac{1}{4} =$
