Odpowiedź:
[tex]3\frac{3}{4}+2\frac{1}{6}=3\frac{9}{12}+2\frac{2}{12}=5\frac{11}{12}[/tex]
[tex]3\frac{3}{4}-2\frac{1}{6}=3\frac{9}{12}-2\frac{2}{12}=1\frac{7}{12}[/tex]
[tex]3\frac{3}{4}*2\frac{1}{6}=\frac{15}{4}*\frac{13}{6}=\frac{65}{8}=8\frac{1}{8}[/tex]
[tex]3\frac{3}{4}:2\frac{1}{6}=\frac{15}{4}:\frac{13}{6}=\frac{15}{4}*\frac{6}{13}=\frac{45}{26}=1\frac{19}{26}[/tex]
