Решите примеры на вычитание:

a) \(2\frac{3}{5} - 1 = 1\frac{3}{5}\) б) \(2\frac{3}{5} - \frac{2}{5} = 2\frac{3-2}{5} = 2\frac{1}{5}\) в) \(1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{5-2}{5} = \frac{3}{5}\) г) \(2\frac{3}{5} - 1\frac{2}{5} = (2-1) + (\frac{3}{5} - \frac{2}{5}) = 1 + \frac{1}{5} = 1\frac{1}{5}\) д) \(4 - \frac{5}{8} = \frac{32}{8} - \frac{5}{8} = \frac{32-5}{8} = \frac{27}{8} = 3\frac{3}{8}\) е) \(2\frac{2}{5} - 1\frac{3}{5} = 2\frac{2}{5} - 1\frac{3}{5} = \frac{12}{5} - \frac{8}{5} = \frac{4}{5}\)
