\(2\frac{3}{5}=\)

\(\frac{12}{10}=\)

\(\frac{10}{3}=\)

\(\frac{15}{6}=\)

\(2\frac{3}{8} + 1\frac{6}{8}=\)

\(\frac{9}{12} - \frac{2}{12}=\)

\(5\frac{7}{10} -4 \frac{5}{10}=\)

\(4\frac{1}{6} - 2\frac{5}{6}=\)

\(3\frac{2}{5} - 1\frac{4}{5}=\)

\(\frac{4}{12} + \frac{6}{12}=\)

\(\left(1\frac{2}{5} + \frac{1}{5}\right)+2\frac{3}{5}=\)

\(2\frac{4}{6} + \left(2\frac{3}{6}+2\frac{2}{6}\right)=\)

\(\frac{3}{10} + \left(2\frac{4}{10}+\frac{7}{10}\right)=\)
