№ 1. Представьте в виде дроби \(\frac{m}{n}\) (\(m \in \mathbb{Z}, n \in \mathbb{N}\)) числа: 18; −4,3; 0; −0,6; 1,4; −3\(\frac{2}{5}\); 4\(\frac{1}{8}\).

1. \(18=\frac{18}{1}\).
2. \(-4,3=-\frac{43}{10}\).
3. \(0=\frac{0}{1}\).
4. \(-0,6=-\frac{6}{10}=-\frac{3}{5}\).
5. \(1,4=\frac{14}{10}=\frac{7}{5}\).
6. \(-3\frac{2}{5}=-\frac{3\cdot5+2}{5}=-\frac{17}{5}\).
7. \(4\frac{1}{8}=\frac{4\cdot8+1}{8}=\frac{33}{8}\).

Ответ: \(\frac{18}{1}; -\frac{43}{10}; \frac{0}{1}; -\frac{3}{5}; \frac{7}{5}; -\frac{17}{5}; \frac{33}{8}\).
