a) [tex]= (\frac{3}{4} -\frac{2}{4} )*\frac{16}{5} =\frac{1}{4} *\frac{16}{5}=1*\frac{4}{5} =\frac{4}{5}[/tex]
b) [tex]=\frac{7}{2} *\frac{1}{5} -1*\frac{2}{7} =\frac{7}{10} -\frac{2}{7} =\frac{49}{70} -\frac{20}{70} =\frac{29}{70}[/tex]
c) = [tex]\frac{7}{3} * (\frac{7}{4} -\frac{7}{8} )=\frac{7}{3} *(\frac{14}{8} -\frac{7}{8})=\frac{7}{3} *\frac{7}{8} =\frac{49}{24} =2\frac{1}{24}[/tex]
d) = [tex]\frac{16}{5} *\frac{1}{2} -\frac{5}{7} *\frac{7}{5} =\frac{8}{5} *1-1*1=\frac{8}{5} -\frac{1}{1} =\frac{8}{5} -\frac{5}{5} =\frac{3}{5}[/tex]
e) = [tex]\frac{1}{5}*(\frac{24}{7} -\frac{2}{7} *\frac{11}{2} ) =\frac{1}{5}*(\frac{24}{7} -\frac{1}{7} *11 )=\frac{1}{5}*(\frac{24}{7} -\frac{11}{7} )=\frac{1}{5}*\frac{13}{7} =\frac{13}{35}[/tex]
