2. Представьте в виде десятичной дроби: a) \(\frac{1}{10}\); б) \(\frac{4}{100}\); в) \(\frac{3}{50}\); г) \(2\frac{1}{2}\); д) \(1\frac{1}{5}\); e) \(3\frac{3}{4}\).

Решим каждый пример пошагово: a) \(\frac{1}{10}\) = 0,1 б) \(\frac{4}{100}\) = 0,04 в) \(\frac{3}{50}\) = \(\frac{3 \times 2}{50 \times 2}\) = \(\frac{6}{100}\) = 0,06 г) \(2\frac{1}{2}\) = \(2 + \frac{1}{2}\) = \(2 + 0,5\) = 2,5 д) \(1\frac{1}{5}\) = \(1 + \frac{1}{5}\) = \(1 + \frac{1 \times 2}{5 \times 2}\) = \(1 + \frac{2}{10}\) = \(1 + 0,2\) = 1,2 e) \(3\frac{3}{4}\) = \(3 + \frac{3}{4}\) = \(3 + \frac{3 \times 25}{4 \times 25}\) = \(3 + \frac{75}{100}\) = \(3 + 0,75\) = 3,75
