$0,95+ frac{5}{12}= frac{95}{100}+ frac{5}{12} = frac{19}{20} + frac{5}{12} = frac{57+25}{60} = frac{82}{60} =1 frac{22}{60} =1 frac{11}{30} \ \ frac{3}{4} + frac{5}{7} = frac{21+20}{28} = frac{41}{28} =1 frac{13}{28} \ \ frac{7}{24}+ frac{7}{60} = frac{14+35}{120} = frac{49}{120} \ \ frac{5}{24} = frac{125}{600} \ frac{7}{50}= frac{84}{600} \ frac{125}{600} textgreater frac{84}{600} \ frac{5}{24} textgreater frac{7}{50} \ \ \ x+ frac{4}{15} = frac{2}{3}+ frac{2}{5} \ x+ frac{4}{15} = frac{10+6}{15} \ x+ frac{4}{15} = frac{16}{15} \ x= frac{16}{15} - frac{4}{15} \ x= frac{12}{15} = frac{4}{5}$
