Odpowiedź:
[tex]-2\frac{1}{4}*2\frac{1}{3}=-\frac{9}{4}*\frac{7}{3}=-\frac{3*7}{4*1}=-\frac{21}{4}=-5\frac{1}{4}[/tex]
[tex]-7\frac{1}{5}:-3\frac{1}{5}=-\frac{36}{5}:(-\frac{16}{5})=-\frac{36}{5}*(-\frac{5}{16})=\frac{36}{16}=\frac{9}{4}=2\frac{1}{4}[/tex]
[tex](-1,4)*(-5,07)=(-\frac{14}{10})*(-\frac{507}{100}=\frac{3549}{500}=7,098[/tex]
[tex](0,056):(-0,7)=-0,08[/tex]
