Решение:
\[ \frac{14}{11} + \frac{17}{10} = \frac{14 \times 10}{11 \times 10} + \frac{17 \times 11}{10 \times 11} = \frac{140}{110} + \frac{187}{110} = \frac{140 + 187}{110} = \frac{327}{110} \]
\[ \frac{327}{110} \times \frac{11}{15} \]
\[ \frac{327}{10} \times \frac{1}{15} = \frac{327}{150} \]
\[ \frac{327 \div 3}{150 \div 3} = \frac{109}{50} \]
\[ \frac{109}{50} = \frac{109 \times 2}{50 \times 2} = \frac{218}{100} = 2.18 \]
Ответ: 109/50 или 2.18
