1)
 frac{13 times 4 times 9}{26 times 27 times 8}  =  frac{1 times 1 times 1}{2 times 3 times 2} =  frac{1}{12}
2)
 frac{17 times 2 times 5}{51 times 25}  =  frac{1 times 2 times 1}{3 times 5}  =  frac{2}{15}
3)
 frac{15 times 13 times 6}{6 times 9 times 26}  =  frac{5 times 1 times 1}{1 times 3 times 2}  =  frac{5}{6}
4)
 frac{49 times 55 times 56}{28 times 66 times 10}  =  frac{49 times 5 times 2}{1 times 6 times 10}  =  frac{49 times 1 times 1}{1 times 3 times 2}  =  frac{49}{6}  = 8 frac{1}{6}
5)
 frac{45 times 8 times 6}{66 times 15 times 18}  =  frac{3 times  4 times 1}{11 times 1 times 9}  =  frac{1 times 4}{11 times 3}  =  frac{4}{33}
6)
 frac{25 times 24 times 14}{28 times 75}  =  frac{1 times 24 times 1}{2 times 3}  =  frac{24}{6}  = 4
7)
 frac{85 times 81 times 39}{27 times 51 times 52}  =  frac{5 times 3 times 3}{1 times 3 times 4}  =  frac{5 times 1 times 3}{1 times 1 times 4}  =  frac{15}{4}  = 3 frac{3}{4}
8)
 frac{76 times 102 times 130 times 108}{162 times 78 times 68 times 114}  =  frac{38 times 17 times 65 times 18}{81 times 13 times 34 times 19}  =  frac{2 times 5 times 2 times 1}{9 times 1 times 2 times  1}  =  frac{10}{9}  =  1frac{1}{9}
