$(1.2 + 1.(3) \times \frac{3}{20} ) \div 0.14 \times 2 = \\ ( \frac{6}{5} + \frac{4}{3} \times \frac{3}{20} ) \div \frac{7}{50} \times 2 = \\ ( \frac{6}{5} + \frac{1}{5} ) \div \frac{7}{50} \times 2 = \\ \frac{7}{5} \div \frac{7}{50} \times 2 = \\ \frac{7}{5} \times \frac{50}{7} \times 2 = \\ 10 \times 2 = 20$
