12. Запишите в виде несократимых дробей: 37% = ; 43% = ; 59% = ; 8% = ; 20% = ; 66% =

Процент — это сотая часть числа: \(p\% = \frac{p}{100}\).

1. \(37\% = \frac{37}{100}\);
2. \(43\% = \frac{43}{100}\);
3. \(59\% = \frac{59}{100}\);
4. \(8\% = \frac{8}{100} = \frac{2}{25}\);
5. \(20\% = \frac{20}{100} = \frac{1}{5}\);
6. \(66\% = \frac{66}{100} = \frac{33}{50}\).

Ответ: 37% = \(\frac{37}{100}\); 43% = \(\frac{43}{100}\); 59% = \(\frac{59}{100}\); 8% = \(\frac{2}{25}\); 20% = \(\frac{1}{5}\); 66% = \(\frac{33}{50}\); 66% = \(\frac{33}{50}\).
