Решите задачу:

$(13 \frac{1}{10} - 12.05) \div \frac{7.2}{0.48} \times 11.7 + (1.25 \times 0.4 + \frac{18.54}{1.8} ) \div (0.43 + 17.57) = \\ ( \frac{131}{10} - 12.05) \div \frac{7.2}{0.48} \times 11.7 + (1.25 \times 0.4 + \frac{18.54}{1.8} ) \div (0.43 + 17.57) = \\ ( \frac{131}{10} - \frac{241}{20}) \div \frac{ \frac{36}{5} }{ \frac{12}{25} } \times \frac{117}{10} + (0.5 + \frac{ \frac{927}{50} }{ \frac{9}{5} } ) \div 18 = \\ \frac{21}{20} \div 15 \times \frac{117}{10} + ( \frac{1}{2} + \frac{103}{10} ) \times \frac{1}{18} = \\ \frac{21}{20} \times \frac{1}{15} \times \frac{117}{10} + \frac{54}{5} \times \frac{1}{18 } = \\ \frac{7}{20} \times \frac{1}{5} \times \frac{117}{10} + \frac{3}{5} = \\ \frac{819}{1000} + \frac{3}{5} = \\ \frac{1419}{1000} = 1 \frac{419}{1000} = 1.419$
