Давай разберемся с этим примером по частям!
\[ \frac{6}{11} : \frac{2}{11} = \frac{6}{11} \times \frac{11}{2} = \frac{6 \times 11}{11 \times 2} = \frac{66}{22} = 3 \]
\[ 3 \times \frac{1}{6} = \frac{3}{6} = \frac{1}{2} \]
\[ \frac{1}{2} : 2 = \frac{1}{2} : \frac{2}{1} = \frac{1}{2} \times \frac{1}{2} = \frac{1 \times 1}{2 \times 2} = \frac{1}{4} \]
\[ \frac{1}{2} + \frac{1}{4} = \frac{1 \times 2}{2 \times 2} + \frac{1}{4} = \frac{2}{4} + \frac{1}{4} = \frac{2+1}{4} = \frac{3}{4} \]
Ответ: $$\frac{3}{4}$$
