Obliczenia

[tex]\frac{5}{6}+\frac{1}{8}=\frac{20}{24}+\frac{3}{24}=\frac{23}{24}\\\\\frac{3}{10}+\frac{1}{5}=\frac{3}{10}+\frac{2}{10}=\frac{5}{10}=\frac{1}{2}\\\\\frac{3}{4}+\frac{5}{7}=\frac{21}{28}+\frac{20}{28}=\frac{41}{28}=1\frac{13}{28}\\\\\frac{5}{8}-\frac{1}{2}=\frac{5}{8}-\frac{4}{8}=\frac{1}{8}[/tex]

Pozdrawiam!
