\[\boxed{\mathbf{2.2}\mathbf{52}}\]

\[\textbf{а)}\ 1 - y = \frac{7}{24} + \frac{1^{\backslash 6}}{4}\]

\[1 - y = \frac{7}{24} + \frac{6}{24}\]

\[1 - y = \frac{13}{24}\]

\[y = 1 - \frac{13}{24} = \frac{24}{24} - \frac{13}{24}\]

\[y = \frac{11}{24}.\]

\[\textbf{б)}\ 1 + m = \frac{3^{\backslash 5}}{5} + \frac{6}{15}\]

\[1 + m = \frac{9}{15} + \frac{6}{15}\]

\[1 + m = \frac{15}{15}\]

\[1 + m = 1\]

\[m = 1 - 1\]

\[m = 0.\]

\[\textbf{в)}\ \ l + 3\frac{5}{6} = 7\frac{1}{6} - 2\frac{2^{\backslash 2}}{3}\]

\[l + 3\frac{5}{6} = 7\frac{1}{6} - 2\frac{4}{6}\]

\[l + 3\frac{5}{6} = 6\frac{7}{6} - 2\frac{4}{6}\]

\[l + 3\frac{5}{6} = 4\frac{3}{6}\]

\[l = 3\frac{9}{6} - 3\frac{5}{6}\]

\[l = \frac{4}{6} = \frac{2}{3}.\]
