Odpowiedź:
a) [tex](3\frac{3}{5} +2\frac{4}{5} ):\frac{6}{7} =5\frac{7}{5} :\frac{6}{7} =\frac{32}{5} * \frac{7}{6} =\frac{112}{15} =7\frac{7}{15}[/tex]
b) [tex]\frac{3}{4} :4\frac{1}{2} +7:1\frac{1}{6} = \frac{3}{4} :\frac{9}{2} +7:\frac{7}{6} = \frac{3}{4} * \frac{2}{9} +7*\frac{6}{7} =\frac{1}{6} +6=6\frac{1}{6}[/tex]
c) [tex]\frac{3}{5} :(1\frac{1}{2} -\frac{3}{4} )=\frac{3}{5} :(1\frac{2}{4} -\frac{3}{4} )=\frac{3}{5} :( \frac{6}{4} -\frac{3}{4} )=\frac{3}{5} :\frac{3}{4} =\frac{3}{5} *\frac{4}{3} =\frac{4}{5}[/tex]
