- а) \(\frac{3,2}{19,2} = \frac{32}{192} = \frac{1}{6}\)
- б) \(\frac{2\frac{6}{7}}{3\frac{3}{14}} = \frac{\frac{20}{7}}{\frac{45}{14}} = \frac{20}{7} \cdot \frac{14}{45} = \frac{20 \cdot 14}{7 \cdot 45} = \frac{4 \cdot 2}{1 \cdot 9} = \frac{8}{9}\)
- в) \(\frac{1,35}{3\frac{3}{4}} = \frac{1,35}{3,75} = \frac{135}{375} = \frac{27}{75} = \frac{9}{25}\)
Ответ: a) \(\frac{1}{6}\); б) \(\frac{8}{9}\); в) \(\frac{9}{25}\)
