Решение:
а) 4$$\frac{3}{13}$$:1$$\frac{7}{26}$$ = $$\frac{55}{13}$$ : $$\frac{33}{26}$$ = $$\frac{55}{13}$$ * $$\frac{26}{33}$$ = $$\frac{5}{1}$$ * $$\frac{2}{3}$$ = $$\frac{10}{3}$$ = 3$$\frac{1}{3}$$
б) 3$$\frac{2}{3}$$:$$\frac{3}{14}$$ = $$\frac{11}{3}$$ : $$\frac{3}{14}$$ = $$\frac{11}{3}$$ * $$\frac{14}{3}$$ = $$\frac{154}{9}$$ = 17$$\frac{1}{9}$$
в) 19,2:$$\frac{3}{5}$$ = 19,2 * $$\frac{5}{3}$$ = $$\frac{192}{10}$$ * $$\frac{5}{3}$$ = $$\frac{64}{2}$$ * $$\frac{1}{1}$$ = 32
г) 1,35:$$\frac{3}{4}$$ = 1,35 * $$\frac{4}{3}$$ = $$\frac{135}{100}$$ * $$\frac{4}{3}$$ = $$\frac{27}{25}$$ * $$\frac{1}{1}$$ = $$\frac{27}{25}$$ = 1$$\frac{2}{25}$$
Ответ: а) 3$$\frac{1}{3}$$ б) 17$$\frac{1}{9}$$ в) 32 г) 1$$\frac{2}{25}$$
