Решим предложенные примеры:
- 6$$\frac{1}{3}$$-8$$\frac{1}{6}$$ = $$\frac{19}{3}$$ - $$\frac{49}{6}$$ = $$\frac{19 \cdot 2}{3 \cdot 2}$$ - $$\frac{49}{6}$$ = $$\frac{38}{6}$$ - $$\frac{49}{6}$$ = -$$\frac{11}{6}$$ = -1$$\frac{5}{6}$$
- 2$$\frac{2}{7}$$-4$$\frac{1}{7}$$ = $$\frac{16}{7}$$ - $$\frac{29}{7}$$ = -$$\frac{13}{7}$$ = -1$$\frac{6}{7}$$
- 1$$\frac{3}{8}$$ : (-$$\frac{11}{16}$$) = $$\frac{11}{8}$$ : (-$$\frac{11}{16}$$) = $$\frac{11}{8}$$\cdot$$(-$$\frac{16}{11}$$) = -$$\frac{11 \cdot 16}{8 \cdot 11}$$ = -$$\frac{16}{8}$$ = -2
- -$$\frac{5}{11}$$\cdot$$\frac{33}{65}$$ = -$$\frac{5 \cdot 33}{11 \cdot 65}$$ = -$$\frac{5 \cdot 3 \cdot 11}{11 \cdot 5 \cdot 13}$$ = -$$\frac{3}{13}$$
- -14: (-2$$\frac{4}{5}$$) = -14 : (-$$\frac{14}{5}$$) = -14$$\cdot$$(-$$\frac{5}{14}$$) = $$\frac{14 \cdot 5}{14}$$ = 5
Ответ: 1) -1$$\frac{5}{6}$$; 2) -1$$\frac{6}{7}$$; 3) -2; 4) -$$\frac{3}{13}$$; 5) 5
