Answer 1

$\frac{(3.9 - 2.55 + 4 \frac{5}{12} - 1 \frac{1}{15} \div 4.7 }{(0.81 \times 8 \frac{1}{3} - 0.57 \div 4 \frac{3}{4}) \div 2.21 + 4.125 \div 2 \frac{1}{16} } = \frac{( \frac{39}{10} - \frac{51}{20} + \frac{53}{12} - \frac{16}{15}) \div \frac{47}{10} }{( \frac{81}{100} \times \frac{25}{3} - \frac{57}{100} \div \frac{19}{4} ) \div \frac{221}{100} + \frac{33}{8} \div \frac{33}{16} } = \frac{ \frac{47}{10} \div \frac{47}{10} }{( \frac{27}{4} - \frac{57}{100} \times \frac{4}{19}) \times \frac{100}{221} + \frac{33}{8} \times \frac{16}{33} } = \frac{1}{( \frac{27}{4} - \frac{3}{25} ) \times \frac{100}{221} + 2 } = \frac{1}{ \frac{663}{100 } \times \frac{100}{221} + 2} = \frac{1}{3 + 2} = \frac{1}{5} = 0.2$
