Б: 1) 5/6 + 7/33 + 9/22; 2) 60/11 : 5/8 · 9/40 + 0,01; 3) (1 − 1/11 + 1/121) : (8/20 + 4/12).

1. Приведём дроби к общему знаменателю 66:

   \(\frac{5}{6}+\frac{7}{33}+\frac{9}{22}=\frac{55}{66}+\frac{14}{66}+\frac{27}{66}=\frac{96}{66}=\frac{16}{11}\).

2. Выполняем деление и умножение слева направо, \(0,01=\frac{1}{100}\):

   \(\frac{60}{11}:\frac{5}{8}\cdot\frac{9}{40}+0,01=\frac{60}{11}\cdot\frac{8}{5}\cdot\frac{9}{40}+\frac{1}{100}=\frac{108}{55}+\frac{1}{100}=\frac{2171}{1100}\).

3. \(1-\frac{1}{11}+\frac{1}{121}=\frac{121-11+1}{121}=\frac{111}{121}\).

   \(\frac{8}{20}+\frac{4}{12}=\frac{2}{5}+\frac{1}{3}=\frac{11}{15}\).

   \(\frac{111}{121}:\frac{11}{15}=\frac{111}{121}\cdot\frac{15}{11}=\frac{1665}{1331}\).

Ответ: 1) \(\frac{16}{11}\); 2) \(\frac{2171}{1100}\); 3) \(\frac{1665}{1331}\).
