Ответ:

  1. Процент — это одна сотая: \(16\% = \frac{16}{100} = \frac{4}{25}\).
  2. \(129\% = \frac{129}{100}\).
  3. \(32{,}6\% = \frac{32{,}6}{100} = 0{,}326 = \frac{163}{500}\).
  4. \(\frac{5}{3}\% = \frac{5}{3} \cdot \frac{1}{100} = \frac{5}{300} = \frac{1}{60}\).

Ответ: 1) \(\frac{4}{25}\); 2) \(\frac{129}{100}\); 3) \(\frac{163}{500}\); 4) \(\frac{1}{60}\).
