Решение:

1. $$\frac{1}{2} = 0.5$$
2. $$\frac{3}{4} = 0.75$$
3. $$\frac{7}{25} = \frac{7 \cdot 4}{25 \cdot 4} = \frac{28}{100} = 0.28$$
4. $$\frac{16}{125} = \frac{16 \cdot 8}{125 \cdot 8} = \frac{128}{1000} = 0.128$$
5. $$\frac{28}{5} = \frac{28 \cdot 2}{5 \cdot 2} = \frac{56}{10} = 5.6$$
6. $$\frac{14}{8} = \frac{7}{4} = \frac{7 \cdot 25}{4 \cdot 25} = \frac{175}{100} = 1.75$$
