Ответ:
\(10\frac{5}{8}-x=7\frac{3}{5}\).
Выразим неизвестное: \(x=10\frac{5}{8}-7\frac{3}{5}\).
НОК(8, 5) = 40: \(10\frac{25}{40}-7\frac{24}{40}=3\frac{1}{40}\).
\((x-2\frac{7}{8})+3\frac{5}{6}=4\frac{2}{3}\).
\(x-2\frac{7}{8}=4\frac{2}{3}-3\frac{5}{6}=\frac{14}{3}-\frac{23}{6}=\frac{28}{6}-\frac{23}{6}=\frac{5}{6}\).
\(x=2\frac{7}{8}+\frac{5}{6}\). НОК(8, 6) = 24: \(2\frac{21}{24}+\frac{20}{24}=3\frac{17}{24}\).
Ответ: 1) \(x=3\frac{1}{40}\); 2) \(x=3\frac{17}{24}\).
