Explicación paso a paso:

$1) \frac{6}{8} +\frac{2}{8} +\frac{5}{8} =\frac{6+2+5}{8} = \frac{13}{8}$

$2) \frac{5}{12} +\frac{9}{12} -\frac{3}{12} = \frac{5+9-3}{12} = \frac{11}{12}$

$3) 1\frac{2}{7} +\frac{4}{7} +2\frac{9}{7} = \frac{7+2}{7} +\frac{4}{7} +\frac{14+9}{7} =\frac{9}{7} +\frac{4}{7} +\frac{23}{7} = \frac{9+4+23}{7} =\frac{36}{7}$

$4) 2\frac{7}{9} -\frac{4}{9} -\frac{7}{9} = \frac{18+7}{9} -\frac{4}{9} -\frac{7}{9}= \frac{25}{9} -\frac{4}{9} -\frac{7}{9} = \frac{25-4-7}{9} = \frac{14}{9}$

$5) 1\frac{5}{11} +\frac{7}{11} +\frac{4}{11} = \frac{11+5}{11} +\frac{7}{11} +\frac{4}{11} =\frac{16}{11} +\frac{7}{11} +\frac{4}{11} = \frac{16+7+4}{11} = \frac{27}{11}$
