Answer 1

$[(6 \frac{1}{6} - 1 \frac{1}{24} ) \div 8.25 + 7.125 + \frac{2}{3}] \div [( \frac{16}{17} - \frac{45}{68} ) \times \frac{17}{20} ] = [( \frac{37}{6} - \frac{25}{24} ) \div \frac{825}{100} + \frac{7125}{1000} + \frac{2}{3} ] \div [( \frac{64 - 45}{68} ) \times \frac{17}{20}] = [ \frac{148 - 25}{24} \times \frac{100}{825} + \frac{7125}{1000} + \frac{2}{3}] \div \frac{19}{68} \times \frac{17}{20}] = [ \frac{123}{24} \times \frac{100}{825} + \frac{7125}{1000} + \frac{2}{3} ] \div \frac{19}{80} = [ \frac{4100}{6600} + \frac{7125}{1000} + \frac{2}{3} ] \times \frac{80}{19} = \frac{20500 + 235125 + 22000}{33000} \times \frac{80}{19} = \frac{277625}{33000} \times \frac{80}{19} = \frac{22210000}{627000} = 35 \frac{26500}{627000}$

$(7.85 + 3.15) \times 1 \frac{2}{5} \div (7.2 \div 2) \times ( \frac{1}{2} \div 0.2) = 11 \times 1.4 \div 3.6 \times( 0.5 \div 0.2) = 15.4 \div 3.6 \times 2.5 = 15.4 \div 9 = \frac{154}{100} \div 9 = \frac{154}{100} \times \frac{1}{9} = \frac{154}{900} = \frac{77}{450}$
