2. Выполните вычитание: 9\frac{11}{12}-3\frac{10}{12} = 11-\frac{5}{18} = 8\frac{3}{17}-4\frac{11}{17} = 9\frac{11}{15}-4 = 21-8\frac{7}{15} = 10\frac{15}{16}-3\frac{15}{16} =

2. Выполните вычитание:

1. $$9\frac{11}{12}-3\frac{10}{12} = (9-3)+\frac{11-10}{12}=6+\frac{1}{12}=6\frac{1}{12}$$
   Ответ: $$6\frac{1}{12}$$
2. $$11-\frac{5}{18} = 10\frac{18}{18}-\frac{5}{18} = 10\frac{18-5}{18} = 10\frac{13}{18}$$
   Ответ: $$10\frac{13}{18}$$
3. $$8\frac{3}{17}-4\frac{11}{17} = 7\frac{20}{17}-4\frac{11}{17} = (7-4)+\frac{20-11}{17} = 3+\frac{9}{17}=3\frac{9}{17}$$
   Ответ: $$3\frac{9}{17}$$
4. $$9\frac{11}{15}-4 = (9-4)+\frac{11}{15} = 5+\frac{11}{15} = 5\frac{11}{15}$$
   Ответ: $$5\frac{11}{15}$$
5. $$21-8\frac{7}{15} = 20\frac{15}{15}-8\frac{7}{15} = (20-8)+\frac{15-7}{15} = 12+\frac{8}{15}=12\frac{8}{15}$$
   Ответ: $$12\frac{8}{15}$$
6. $$10\frac{15}{16}-3\frac{15}{16} = (10-3)+\frac{15-15}{16} = 7+\frac{0}{16} = 7$$
   Ответ: 7
