a) 8$$\frac{9}{11}$$ – 3$$\frac{5}{11}$$ = (8-3) + $$\frac{9-5}{11}$$ = 5$$\frac{4}{11}$$
Ответ: 5$$\frac{4}{11}$$
б) 6$$\frac{5}{8}$$ – 4 = (6-4) + $$\frac{5}{8}$$ = 2$$\frac{5}{8}$$
Ответ: 2$$\frac{5}{8}$$
в) 9 – $$\frac{5}{6}$$ = 8$$\frac{6}{6}$$ - $$\frac{5}{6}$$ = 8$$\frac{6-5}{6}$$ = 8$$\frac{1}{6}$$
Ответ: 8$$\frac{1}{6}$$
г) 9 – 3$$\frac{5}{8}$$ = (9-3) - $$\frac{5}{8}$$ = 6 - $$\frac{5}{8}$$ = 5$$\frac{8}{8}$$ - $$\frac{5}{8}$$ = 5$$\frac{3}{8}$$
Ответ: 5$$\frac{3}{8}$$
д) 8$$\frac{2}{7}$$ – 3$$\frac{5}{7}$$ = (8-3) + $$\frac{2-5}{7}$$ = 5 - $$\frac{3}{7}$$ = 4$$\frac{7}{7}$$ - $$\frac{3}{7}$$ = 4$$\frac{4}{7}$$
Ответ: 4$$\frac{4}{7}$$
e) 8$$\frac{3}{8}$$ – 5$$\frac{3}{8}$$ = (8-5) + $$\frac{3-3}{8}$$ = 3 + 0 = 3
Ответ: 3
