Odpowiedź:
[tex]a.-\frac{11}{4}*\frac{5}{2}=-\frac{55}{8}=-6\frac{7}{8}[/tex]
[tex]b.-\frac{36}{5}:(-\frac{21}{5})=-\frac{36}{5}*(-\frac{5}{21})=\frac{12*1}{1*7}=\frac{12}{7}=1\frac{5}{7}[/tex]
[tex]c.-\frac{25}{10} *(-\frac{408}{100})=\frac{102}{10}=10\frac{2}{10}=10\frac{1}{5}[/tex]
[tex]d.0,028:(-0,07)=\frac{28}{1000}*(-\frac{100}{7}=-\frac{4}{10}=-\frac{2}{5}[/tex]
[tex]e.\frac{17}{5}*\frac{10}{12}+\frac{5}{3}*\frac{18}{5}=\frac{34}{12}+6=2\frac{5}{6}+6=8\frac{5}{6}[/tex]
[tex]f.3\frac{1}{6}+(-6\frac{4}{10}-(-4\frac{1}{3})=3\frac{5}{30}-6\frac{12}{30}+4\frac{10}{30}=7\frac{15}{30}-6\frac{12}{30}=1\frac{1}{10}=1,1[/tex]
