[latex] C\\frac{1 frac{5}{6} -0,625}{ frac{4}{13} - frac{25}{39} } = frac{frac{11}{6} - frac{625}{1000} }{ frac{12}{39} - frac{25}{39} } =frac{frac{11}{6} - frac{5}{8} }{ - frac{13}{39} } =frac{frac{44}{24} - frac{15}{24} }{ - frac{1}{3} } =frac{ frac{29}{24} }{ - frac{1}{3} }= frac{29}{24} *(- frac{3}{1})=\=frac{29}{8} *(- frac{1}{1})=- frac{29}{8} =-3 frac{5}{8} [/latex]

[latex]frac{1frac{5}{6}-0,625}{frac{4}{13}-frac{25}{39}} = frac{frac{11}{6}-frac{625}{1000}}{frac{12}{39}-frac{25}{39}}=frac{frac{11}{6}-frac{5}{8}}{-frac{13}{39}}=frac{frac{44}{24}-frac{15}{24}}{-frac{1}{3}}=frac{29}{24}cdot(-frac{3}{1})=-frac{29}{8}=-3frac{5}{8}=-3,625[/latex]
