Szczegółowe wyjaśnienie:
[tex](5\frac{1}{5}:0,6)*3=(\frac{26}{5}:\frac{6}{10})*3=(\frac{26}{5}*\frac{10}{6})*3=(\frac{13}{1}*\frac{2}{3})*3=\frac{26}{3} *\frac{3}{1}=26[/tex]
[tex]3(5\frac{1}{5}:0,6) = 3(\frac{26}{5}:\frac{6}{10}) = 3(\frac{26}{5}:\frac{5}{3}) = 3(\frac{26}{5}\cdot\frac{5}{3}) =3\cdot\frac{26}{3} = \boxed{26}\\\\\underline{Odp. \ C.}[/tex]
