Answer 1

$1) \frac{1}{2} +\frac{5}{8} =\frac{4}{8} +\frac{5}{8} =\frac{9}{8} =1,125\\\\2)\frac{7}{10} -\frac{3}{5} =\frac{7}{10} -\frac{6}{10} =\frac{1}{10} =0,1\\\\3) \frac{1}{3} +\frac{1}{7} =\frac{7}{21} +\frac{3}{21} =\frac{10}{21} \\\\4) \frac{5}{9} -\frac{5}{12} =\frac{20}{36} -\frac{15}{36} =\frac{5}{36} \\\\5) \frac{5}{6} +\frac{3}{8} =\frac{20}{24} +\frac{9}{23} =\frac{29}{23} =1\frac{6}{23} \\\\6) \frac{1}{2} +\frac{7}{9} =\frac{9}{18} +\frac{14}{18} =\frac{23}{18} =1\frac{5}{18}$
