Выполни деление двух дробей. 10 2 30 1 3 18 3 25'4 82 9'3 14 3 25.여 3 32 10 35

1. $$\frac{10}{30} : 1\frac{2}{3} = \frac{10}{30} : \frac{5}{3} = \frac{10}{30} \cdot \frac{3}{5} = \frac{10 \cdot 3}{30 \cdot 5} = \frac{30}{150} = \frac{1}{5}$$
2. $$\frac{18}{25} : \frac{3}{4} = \frac{18}{25} \cdot \frac{4}{3} = \frac{18 \cdot 4}{25 \cdot 3} = \frac{72}{75} = \frac{24}{25}$$
3. $$\frac{8}{9} : \frac{2}{3} = \frac{8}{9} \cdot \frac{3}{2} = \frac{8 \cdot 3}{9 \cdot 2} = \frac{24}{18} = \frac{4}{3} = 1\frac{1}{3}$$
4. $$\frac{14}{25} : \frac{3}{5} = \frac{14}{25} \cdot \frac{5}{3} = \frac{14 \cdot 5}{25 \cdot 3} = \frac{70}{75} = \frac{14}{15}$$
5. $$\frac{3}{10} : \frac{32}{35} = \frac{3}{10} \cdot \frac{35}{32} = \frac{3 \cdot 35}{10 \cdot 32} = \frac{105}{320} = \frac{21}{64}$$
