2. Сократите дроби: a) \(\frac{6}{14}\); б) \(\frac{4}{16}\); в) \(\frac{90}{450}\)

a) \(\frac{6}{14} = \frac{2 \cdot 3}{2 \cdot 7} = \frac{3}{7}\) б) \(\frac{4}{16} = \frac{4 \cdot 1}{4 \cdot 4} = \frac{1}{4}\) в) \(\frac{90}{450} = \frac{9 \cdot 10}{9 \cdot 50} = \frac{10}{50} = \frac{1 \cdot 10}{5 \cdot 10} = \frac{1}{5}\)
