Решим примеры:
- а) $$4\frac{3}{13}:1\frac{7}{26} = \frac{4 \cdot 13 + 3}{13} : \frac{1 \cdot 26 + 7}{26} = \frac{55}{13} : \frac{33}{26} = \frac{55}{13} \cdot \frac{26}{33} = \frac{55 \cdot 26}{13 \cdot 33} = \frac{5 \cdot 2}{1 \cdot 3} = \frac{10}{3} = 3\frac{1}{3}$$
- б) $$\frac{4\frac{2}{7}}{3\frac{3}{14}} = \frac{\frac{4 \cdot 7 + 2}{7}}{\frac{3 \cdot 14 + 3}{14}} = \frac{\frac{30}{7}}{\frac{45}{14}} = \frac{30}{7} : \frac{45}{14} = \frac{30}{7} \cdot \frac{14}{45} = \frac{30 \cdot 14}{7 \cdot 45} = \frac{2 \cdot 2}{1 \cdot 3} = \frac{4}{3} = 1\frac{1}{3}$$
- в) $$\frac{3,2}{19,2} = \frac{32}{192} = \frac{16 \cdot 2}{16 \cdot 12} = \frac{2}{12} = \frac{1}{6}$$
- г) $$1,35:3\frac{3}{4} = 1,35 : \frac{3 \cdot 4 + 3}{4} = 1,35 : \frac{15}{4} = 1,35 \cdot \frac{4}{15} = \frac{1,35 \cdot 4}{15} = \frac{5,4}{15} = \frac{54}{150} = \frac{27}{75} = \frac{9}{25} = 0,36$$
Ответ: a) $$3\frac{1}{3}$$, б) $$1\frac{1}{3}$$, в) $$\frac{1}{6}$$, г) $$0,36$$
