Ответ:
Чтобы выразить процент дробью, делим число процентов на 100 и сокращаем дробь.
1) \(36\% = \frac{36}{100} = \frac{9}{25}\); \(140\% = \frac{140}{100} = \frac{7}{5}\); \(259\% = \frac{259}{100}\); \(400\% = \frac{400}{100} = 4\); \(6{,}5\% = \frac{6.5}{100} = \frac{13}{200}\); \(81{,}3\% = \frac{81.3}{100} = \frac{813}{1000}\).
2) \(\frac{1}{2}\% = \frac{1}{200}\); \(1\frac{1}{4}\% = \frac{5}{4}\cdot\frac{1}{100} = \frac{1}{80}\); \(7\frac{1}{5}\% = \frac{36}{5}\cdot\frac{1}{100} = \frac{9}{125}\); \(3\frac{1}{3}\% = \frac{10}{3}\cdot\frac{1}{100} = \frac{1}{30}\); \(33\frac{1}{3}\% = \frac{100}{3}\cdot\frac{1}{100} = \frac{1}{3}\); \(7\frac{1}{7}\% = \frac{50}{7}\cdot\frac{1}{100} = \frac{1}{14}\).
