Accepted Answer

\(2\frac{1}{8}+5=7\frac{1}{8}\); \(2\frac{1}{5}+\frac{2}{5}=2\frac{3}{5}\); \(8\frac{7}{14}+10\frac{3}{14}=18\frac{10}{14}=18\frac{5}{7}\).
\(7+4\frac{9}{22}=11\frac{9}{22}\); \(1\frac{5}{9}+9\frac{3}{9}=10\frac{8}{9}\); \(15\frac{12}{18}+7\frac{5}{18}=22\frac{17}{18}\).
\(\frac{1}{6}+6\frac{2}{6}=6\frac{3}{6}=6\frac{1}{2}\); \(3\frac{6}{11}+5\frac{4}{11}=8\frac{10}{11}\); \(23\frac{19}{25}+6\frac{1}{25}=30\frac{20}{25}=30\frac{4}{5}\).
