Accepted Answer

\(1\frac{17}{33}+\frac{5}{22}=1+\frac{34}{66}+\frac{15}{66}=1\frac{49}{66}\).
\(1\frac{5}{12}-\frac{7}{10}=1+\frac{25}{60}-\frac{42}{60}=\frac{49}{60}\).
\(7\frac{7}{8}-1\frac{9}{10}=6+\frac{35}{40}-\frac{36}{40}=5\frac{39}{40}\).
\(12\frac{3}{10}-5\frac{11}{15}=7+\frac{9}{30}-\frac{22}{30}=6\frac{17}{30}\).
\(7\frac{7}{15}-1\frac{3}{20}=6+\frac{28}{60}-\frac{9}{60}=6\frac{19}{60}\).
\(5\frac{1}{9}+3\frac{2}{5}=8+\frac{5}{45}+\frac{18}{45}=8\frac{23}{45}\).
\(3\frac{3}{8}+1\frac{5}{12}=4+\frac{9}{24}+\frac{10}{24}=4\frac{19}{24}\).
\(62\frac{2}{3}-3\frac{5}{8}=59+\frac{16}{24}-\frac{15}{24}=59\frac{1}{24}\).
\(12-10\frac{7}{9}=1\frac{2}{9}\).
\(18-11\frac{8}{13}=6\frac{5}{13}\).
\(15\frac{3}{17}-4=11\frac{3}{17}\).
\(2\frac{1}{3}-\frac{4}{5}=1+\frac{5}{15}-\frac{12}{15}=\frac{8}{15}\).
\(16\frac{1}{4}+\frac{5}{8}=16\frac{7}{8}\).
