$9 \frac{1}{23} \times (14 \times \frac{11}{40} \div 7 \frac{7}{10} ) \div 4 \div ( \frac{39}{115} \times 3 \frac{1}{3} ) = \frac{208}{23} \times \frac{14 \times 11 \times 10}{40 \times 77} \div 4 \div \frac{39 \times 10}{115 \times 3} = \frac{208 \times 2 }{23 \times 4 } \times \frac{1}{4} \div \frac{13 \times 2}{23} = \frac{13 \times 2 \times 23}{23 \times 13 \times 2} = 1 \\$

$\frac{133}{135} \div ( \frac{19}{75} \div ( \frac{29}{60} \times 3 \div 7 \frac{1}{4} )) \times 20 \frac{4}{7} \div 24 = \frac{133}{135} \div ( \frac{19}{75} \div \frac{29 \times 3 \times 4}{60 \times 29} ) \times \frac{144}{7} \times \frac{1}{24} = \frac{133}{135} \div \frac{19 \times 60 \times 29}{75 \times 29 \times 3 \times 4} \times \frac{6}{7} = \frac{133}{135} \div \frac{19 }{15 } \times \frac{6}{7} = \frac{133 \times 15 \times 6}{135 \times 19 \times 7} = \frac{7 \times 6}{9 \times 7} = \frac{2}{3} \\$

▪

$( \frac{5}{11} \times 2 \frac{2}{11} ) \div (0.6 \div 1.1) \div (2 \times \frac{5}{88} ) \div 32 = \frac{5 \times 24}{11 \times 11} \div \frac{6 \times 10}{10 \times 11} \div \frac{5}{44 \times 32} = \frac{5 \times 24 \times 10 \times 11 \times 44 }{11 \times 11 \times 6 \times 10 \times 5×32} = \frac{1}{2} \\$

▪

$3 \div (2.75 \div (1 \frac{2}{63} \div \frac{1}{7} \div 13) \times \frac{5}{66} ) \times 0.05 = 3 \div (\frac{275}{100} \div ( \frac{65 \times 7}{63 \times 13} ) \times \frac{5}{66} ) \times \frac{5}{100} = 3 \div (\frac{11}{4} \div \frac{5}{9} \times \frac{5}{6} ) \times \frac{1}{20} = 3 \div ( \frac{11 \times 9 \times 5}{4 \times 5 \times 66} ) \times \frac{1}{20} = 3 \div \frac{ 3}{8 } \times \frac{1}{20} = \frac{3 \times 8}{3\times 20} = \frac{2}{5} \\$
