Odpowiedź:
[tex]2,5+1\frac{2}{3}=2\frac{1}{2}+1\frac{2}{3}=2\frac{3}{6}+1\frac{4}{6}=3\frac{7}{6}=4\frac{1}{6}[/tex]
[tex]3\frac{4}{5}+2,75 = 3,80+2,75 = 6,55[/tex]
[tex]4\frac{5}{6}-1,5=4\frac{5}{6}-1\frac{1}{2}=4\frac{5}{6}-1\frac{3}{6}=3\frac{2}{6}=3\frac{1}{3}[/tex]
[tex]3,125*\frac{4}{15}=3\frac{125}{1000}*\frac{4}{15}=3\frac{1}{8}*\frac{4}{15}=\frac{25}{8}*\frac{4}{15}=\frac{5}{6}[/tex]
