Question

$\frac{4}{7} . (-2) -1-\frac{1}{4 } . (2 -\frac{1}{3} )$
$(\frac{1}{9} -\frac{7}{6} ) . (\frac{6}{5} - \frac{3}{10} ) : (\frac{1}{2} +\frac{3}{4} )$

Answer 1

$\frac{4}{7}*(-2)-1-\frac{1}{4}*(2-\frac{1}{3})=-\frac{8}{7}-1-\frac{1}{4}(\frac{5}{3})=-\frac{15}{7}-\frac{5}{12}=-\frac{215}{84}$

$(\frac{1}{9}-\frac{7}{6})*(\frac{6}{5}-\frac{3}{10}):(\frac{1}{2}+\frac{3}{4})=(-\frac{19}{18})*(\frac{9}{10}):(\frac{5}{4})=(-\frac{19}{20}):(\frac{5}{4})=\frac{-19*4}{20*5}=-\frac{19}{25}$
