Answer 1

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

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

▪

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

▪

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