$1. \frac{5}{8} + \frac{5}{6} + \frac{7}{12} = \frac{30}{48} + \frac{40}{48} + \frac{14}{48} = \frac{84}{48 }$

$2. \frac{1}{5} + \frac{3}{8} + \frac{2}{9} = \frac{23}{40} + \frac{2}{9} = \frac{207}{360} + \frac{80}{360} = \frac{287}{360}$

$3. \frac{1}{4} + \frac{2}{9} + \frac{5}{36} = \frac{9}{36} + \frac{8}{36} + \frac{5}{36} = \frac{22}{36}$

$4. \frac{3}{4} + \frac{4}{5} + \frac{1}{2} = \frac{15}{20} + \frac{16}{20} + \frac{10}{20} = \frac{41}{20}$

$5. \frac{3}{4} + \frac{5}{12} - \frac{1}{9} = \frac{27}{36} + \frac{10}{36} + \frac{4}{36} = \frac{41}{36}$

$6. \frac{4}{15} + \frac{2}{5} + \frac{7}{10} = \frac{8}{30} + \frac{12}{30} + \frac{21}{30} = \frac{41}{30}$
