[tex]\frac{\frac{5}{8}-\frac{1}{2}}{\frac{3}{4}-\frac{1}{2}} = \frac{\frac{5}{8}-\frac{4}{8}}{\frac{3}{4}-\frac{2}{4}} = \frac{\frac{1}{8}}{\frac{1}{4}} = \frac{1}{8}\cdot\frac{4}{1} =\frac{4}{8} = \frac{1}{2}[/tex]
[tex]Lub\\\\\frac{\frac{5}{8}-\frac{1}{2}}{\frac{3}{4}-\frac{1}{2}}=\frac{0,625-0,5}{0,75-0,5} = \frac{0,125}{0,25} =\frac{125}{250} = 0,5[/tex]
