1 Вычисли: a) 8-611 10 в) B) 10-96 1 15 15 )9-36 17 17

a) 8 - 6$$\frac{11}{10}$$ = 8 - $$\frac{60+11}{10}$$ = 8 - $$\frac{71}{10}$$ = 8 - 7$$\frac{1}{10}$$ = $$\frac{10}{10}$$ - $$\frac{1}{10}$$ = 1$$\frac{10-1}{10}$$ = 1$$\frac{9}{10}$$.

в) 10 - 9$$\frac{6}{15}$$ = 10 - $$\frac{9 \cdot 15 + 6}{15}$$ = 10 - $$\frac{135 + 6}{15}$$ = 10 - $$\frac{141}{15}$$ = 10 - 9$$\frac{6}{15}$$ = 1$$\frac{15}{15}$$ - $$\frac{6}{15}$$ = $$\frac{15-6}{15}$$ = $$\frac{9}{15}$$ = $$\frac{3}{5}$$.

д) 9 - 3$$\frac{6}{17}$$ = 9 - $$\frac{3 \cdot 17 + 6}{17}$$ = 9 - $$\frac{51 + 6}{17}$$ = 9 - $$\frac{57}{17}$$ = 9 - 3$$\frac{6}{17}$$ = 6 - $$\frac{6}{17}$$ = 5$$\frac{17}{17}$$ - $$\frac{6}{17}$$ = 5$$\frac{17-6}{17}$$ = 5$$\frac{11}{17}$$.

Ответ: a) 1$$\frac{9}{10}$$; в) $$\frac{3}{5}$$; д) 5$$\frac{11}{17}$$
