Odpowiedź:
[tex]\frac{15}{27} *\frac{9}{20} =\frac{1}{4}[/tex]
[tex]1\frac{3}{4} *\frac{8}{5} =\frac{7}{4} *\frac{8}{5} =\frac{14}{5} =2\frac{4}{5}[/tex]
[tex](1+\frac{3}{4} ):(\frac{5}{6} -\frac{1}{6} )=1\frac{3}{4} :\frac{4}{6} =\frac{7}{4} *\frac{6}{4} =\frac{7}{4} *\frac{3}{2} =\frac{21}{8} =2\frac{5}{8}[/tex]
[tex]\frac{15}{10} :10=\frac{3}{2}*\frac{1}{10} =\frac{3}{20}[/tex]
[tex]2:\frac{4}{5} =2*\frac{5}{4} =\frac{5}{2} =2\frac{1}{2}[/tex]
