а) \(11\frac{2}{7} + 4\frac{3}{7} - 6\frac{4}{7} = 15\frac{5}{7} - 6\frac{4}{7} = 9\frac{1}{7}\)

б) \(26\frac{7}{19} - 13\frac{4}{19} + 5\frac{2}{19} = 13\frac{3}{19} + 5\frac{2}{19} = 18\frac{5}{19}\)

в) \(44\frac{2}{9} + 8\frac{5}{9} - \frac{7}{9} = 52\frac{7}{9} - \frac{7}{9} = 52\)

г) \(5\frac{7}{10} + 3\frac{9}{10} + 1\frac{3}{10} = 8\frac{16+3}{10} = 9\frac{9}{10}\)

д) \(3\frac{17}{100} - 2\frac{13}{100} - 1 = 1\frac{4}{100} - 1 = \frac{104}{100} - \frac{100}{100} = \frac{4}{100} = 0,04\)

e) \(8 - 4\frac{31}{100} - 2\frac{57}{100} = 4\frac{69}{100} - 2\frac{57}{100} = 2\frac{12}{100} = 2,12\)
