\[\boxed{\mathbf{2.}\mathbf{207}\mathbf{.\ ОК\ ГДЗ - домашка\ на\ }5}\]
Пояснение.
Решение.
\[\textbf{а)}\ 5\frac{7}{15} - \frac{3}{20} = 5\frac{28}{60} - \frac{9}{60} = 5\frac{19}{60}\]
\[\textbf{б)}\ 4\frac{7^{\backslash 3}}{12} - \frac{2}{9} = 4\frac{21}{36} - \frac{8}{36} = 4\frac{13}{36}\]
\[\textbf{в)}\ 6\frac{5^{\backslash 2}}{7} - \frac{3}{14} = 6\frac{10}{14} - \frac{3}{14} =\]
\[= 6\frac{7}{14} = 6\frac{1}{2}\]
\[\textbf{г)}\ 7\frac{5^{\backslash 3}}{7} - 4\frac{2^{\backslash 7}}{3} = 7\frac{15}{21} - 4\frac{14}{21} =\]
\[= 3\frac{1}{21}\]
\[\textbf{д)}\ 3\frac{2^{\backslash 11}}{3} - 3\frac{4^{\backslash 3}}{11} =\]
\[= 3\frac{22}{33} - 3\frac{12}{33} = \frac{10}{33}\]
\[\textbf{е)}\ 7\frac{5^{\backslash 3}}{12} - 3\frac{2^{\backslash 4}}{9} = 7\frac{15}{36} - 3\frac{8}{36} =\]
\[= 4\frac{7}{36}\]
