Accepted Answer

\(1\frac{2}{3}+1\frac{2}{3}=3\frac{1}{3}\).
\(7\frac{4}{5}+1\frac{1}{3}=9\frac{2}{15}\).
\(2\frac{3}{4}+12\frac{2}{3}=15\frac{5}{12}\).
\(6\frac{3}{10}-1\frac{1}{15}=5\frac{1}{6}\).
\(5\frac{11}{12}-2\frac{3}{8}=3\frac{13}{24}\).
\(11\frac{7}{8}-11\frac{5}{6}=\frac{1}{24}\).
\(44\frac{1}{4}-\frac{1}{6}=44\frac{1}{12}\).
\(11\frac{3}{14}+2\frac{1}{6}=13\frac{8}{21}\).
\(2\frac{1}{15}-1\frac{5}{21}=\frac{19}{35}\).
\(5\frac{2}{7}+7\frac{2}{5}=12\frac{24}{35}\).
\(6\frac{1}{2}+3\frac{3}{4}=10\frac{1}{4}\).
\(12\frac{1}{2}+2\frac{1}{3}=14\frac{5}{6}\).
