Решение:

• \(\frac{1}{2}\) + \(\frac{1}{4}\) - \(\frac{3}{8}\) = \(\frac{4}{8}\) + \(\frac{2}{8}\) - \(\frac{3}{8}\) = \(\frac{6}{8}\) - \(\frac{3}{8}\) = \(\frac{3}{8}\)
• 1 - \(\frac{7}{8}\) + \(\frac{1}{4}\) = \(\frac{8}{8}\) - \(\frac{7}{8}\) + \(\frac{2}{8}\) = \(\frac{1}{8}\) + \(\frac{2}{8}\) = \(\frac{3}{8}\)
• \(\frac{1}{8}\) + \(\frac{3}{4}\) - \(\frac{1}{2}\) = \(\frac{1}{8}\) + \(\frac{6}{8}\) - \(\frac{4}{8}\) = \(\frac{7}{8}\) - \(\frac{4}{8}\) = \(\frac{3}{8}\)
• 1 - \(\frac{3}{4}\) + \(\frac{1}{8}\) = \(\frac{8}{8}\) - \(\frac{6}{8}\) + \(\frac{1}{8}\) = \(\frac{2}{8}\) + \(\frac{1}{8}\) = \(\frac{3}{8}\)
• \(\frac{7}{8}\) + \(\frac{1}{8}\) - \(\frac{3}{4}\) = \(\frac{8}{8}\) - \(\frac{6}{8}\) = \(\frac{2}{8}\) = \(\frac{1}{4}\)
• 1 - \(\frac{3}{8}\) + \(\frac{1}{4}\) = \(\frac{8}{8}\) - \(\frac{3}{8}\) + \(\frac{2}{8}\) = \(\frac{5}{8}\) + \(\frac{2}{8}\) = \(\frac{7}{8}\)
• \(\frac{3}{10}\) + \(\frac{1}{5}\) - \(\frac{1}{10}\) = \(\frac{3}{10}\) + \(\frac{2}{10}\) - \(\frac{1}{10}\) = \(\frac{5}{10}\) - \(\frac{1}{10}\) = \(\frac{4}{10}\) = \(\frac{2}{5}\)
• \(\frac{2}{5}\) + \(\frac{1}{10}\) - \(\frac{3}{10}\) = \(\frac{4}{10}\) + \(\frac{1}{10}\) - \(\frac{3}{10}\) = \(\frac{5}{10}\) - \(\frac{3}{10}\) = \(\frac{2}{10}\) = \(\frac{1}{5}\)
• \(\frac{7}{10}\) + \(\frac{1}{5}\) - \(\frac{2}{5}\) = \(\frac{7}{10}\) + \(\frac{2}{10}\) - \(\frac{4}{10}\) = \(\frac{9}{10}\) - \(\frac{4}{10}\) = \(\frac{5}{10}\) = \(\frac{1}{2}\)
