\[\textbf{а)}\ 4\frac{13}{24} + \frac{1}{8} - 3\frac{1}{24} =\]
\[= \left( 4\frac{13}{24} - 3\frac{1}{24} \right) + \frac{1}{8} =\]
\[= 1\frac{12}{24} + \frac{1}{8} = 1\frac{4}{8} + \frac{1}{8} = 1\frac{5}{8}\]
\[\textbf{б)}\ 3\frac{8}{9} + 1\frac{3}{4} + \frac{1}{9} =\]
\[= \left( 3\frac{8}{9} + \frac{1}{9} \right) + 1\frac{3}{4} = 3\frac{9}{9} + 1\frac{3}{4} =\]
\[= 4 + 1\frac{3}{4} = 5\frac{3}{4}\]
\[\textbf{в)}\ 5\frac{1}{2} - 2\frac{7}{12} - 2\frac{3}{10} =\]
\[= 5\frac{6}{12} - 2\frac{7}{12} - 2\frac{3}{10} =\]
\[= 4\frac{18}{12} - 2\frac{7}{12} - 2\frac{3}{10} =\]
\[= 2\frac{11^{\backslash 5}}{12} - 2\frac{3^{\backslash 6}}{10} =\]
\[= 2\frac{55}{60} - 2\frac{18}{60} = \frac{37}{60}\]

\[= 4\frac{8}{12} + 2\frac{9}{12} - 1\frac{5}{12} =\]
\[= 6\frac{17}{12} - 1\frac{5}{12} = 5\frac{12}{12} = 6\]
