Ответ:

Решение:

• \(\frac{1}{2}\) часа - \(\frac{1}{4}\) часа = \(\frac{2}{4}\) - \(\frac{1}{4}\) = \(\frac{1}{4}\) часа
• \(\frac{1}{5}\) м - \(\frac{1}{10}\) м = \(\frac{2}{10}\) - \(\frac{1}{10}\) = \(\frac{1}{10}\) м
• \(\frac{4}{5}\) - \(\frac{7}{10}\) = \(\frac{8}{10}\) - \(\frac{7}{10}\) = \(\frac{1}{10}\)
• 1 - \(\frac{3}{8}\) = \(\frac{8}{8}\) - \(\frac{3}{8}\) = \(\frac{5}{8}\)
• \(\frac{1}{4}\) кг - \(\frac{1}{8}\) кг = \(\frac{2}{8}\) - \(\frac{1}{8}\) = \(\frac{1}{8}\) кг
• \(\frac{4}{5}\) км - \(\frac{1}{10}\) км = \(\frac{8}{10}\) - \(\frac{1}{10}\) = \(\frac{7}{10}\) км
• \(\frac{3}{5}\) - \(\frac{3}{10}\) = \(\frac{6}{10}\) - \(\frac{3}{10}\) = \(\frac{3}{10}\)
• 1 - \(\frac{1}{4}\) = \(\frac{4}{4}\) - \(\frac{1}{4}\) = \(\frac{3}{4}\)
