Задание №1. Решение примеров:
- \( \frac{1}{3} + \frac{2}{6} = \frac{2}{6} + \frac{2}{6} = \frac{4}{6} = \frac{2}{3} \)
- \( \frac{4}{7} - \frac{2}{7} = \frac{2}{7} \)
- \( \frac{3}{5} \times \frac{5}{6} = \frac{3 \times 5}{5 \times 6} = \frac{15}{30} = \frac{1}{2} \)
- \( 1 \frac{1}{3} : \frac{1}{6} = \frac{4}{3} : \frac{1}{6} = \frac{4}{3} \times 6 = \frac{4 \times 6}{3} = \frac{24}{3} = 8 \)
Ответ: а) \( \frac{2}{3} \), б) \( \frac{2}{7} \), в) \( \frac{1}{2} \), г) 8.
