Ответ:
Решение:
- \( \frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = \frac{1}{2} \)
- \( \frac{3}{7} - \frac{2}{9} = \frac{27}{63} - \frac{14}{63} = \frac{13}{63} \)
- \( \frac{16}{35} \)
- \( \frac{4}{9} \cdot 18 = \frac{4 \cdot 18}{9} = 4 \cdot 2 = 8 \)
- \( \frac{46}{75} : \frac{23}{45} = \frac{46}{75} \cdot \frac{45}{23} = \frac{46 \cdot 45}{75 \cdot 23} = \frac{2 \cdot 23 \cdot 3 \cdot 15}{5 \cdot 15 \cdot 23} = \frac{2 \cdot 3}{5} = \frac{6}{5} = 1 \frac{1}{5} \)
- \( \frac{2}{3} : \frac{4}{3} = \frac{2}{3} \cdot \frac{3}{4} = \frac{2}{4} = \frac{1}{2} \)
Ответ: 1) 1/2; 2) 13/63; 3) 16/35; 4) 8; 5) 1 1/5; 6) 1/2.
