[tex]2\frac{1}{2}-\frac{1}{3}=2\frac{3}{6}-\frac{2}{6}=2\frac{1}{6}\\\\1\frac{1}{4}-\frac{1}{8}=1\frac{2}{8}-\frac{1}{8}=1\frac{1}{8}\\\\2\frac{1}{3}+\frac{1}{4}=2\frac{4}{12}+\frac{3}{12}=2\frac{7}{12}[/tex]
Odpowiedź:
2 i 1/2 - 1/3 = 2 i 3/6 - 2/6 = 2 i 1/6
1 i 1/4 - 1/8 = 1 i 2/8 - 1/8 = 1 i 1/8
2 i 1/3 + 1/4 = 2 i 4/12 + 3/12 = 2 i 7/12
