Szczegółowe wyjaśnienie:
a) [tex]\frac{16}{3} *\frac{3}{2} -6*\frac{3}{14} =8-\frac{18}{14} =8-\frac{9}{7} =\frac{56}{7} -\frac{9}{7} =\frac{47}{7} =6\frac{5}{7}[/tex]
b) [tex]\frac{16}{5} *(\frac{5}{2}-\frac{5}{4}*\frac{1}{6} )=\frac{16}{5} *(\frac{5}{2}-\frac{5}{24} )=\frac{16}{5} *(\frac{60}{24}-\frac{5}{24} )=\frac{16}{5} *\frac{55}{24} =\frac{22}{3} =7\frac{1}{3}[/tex]
c) [tex]\frac{10}{7} *(\frac{5}{2}*\frac{2}{3} -\frac{4}{3}*\frac{7}{8} )=\frac{10}{7} *(\frac{5}{3}-\frac{7}{6} )=\frac{10}{7} *(\frac{10}{6}-\frac{7}{6} )=\frac{10}{7} *\frac{3}{6} =\frac{30}{42}[/tex]
d) [tex]\frac{\frac{39}{7} -\frac{9}{7} }{\frac{10}{3}*(\frac{5}{4}-\frac{1}{2} ) } =\frac{\frac{30}{7} }{\frac{10}{3}*(\frac{5}{4}-\frac{2}{4} ) } = \frac{\frac{30}{7} }{\frac{10}{3} *\frac{3}{4} }=\frac{\frac{30}{7} }{\frac{5}{2} } =\frac{30}{7} *\frac{2}{5} =\frac{12}{7} =1\frac{5}{7}[/tex]
