Answer 1

$(frac{12}{13}* frac{14}{17})*( frac{17}{14}* frac{13}{24})= frac{1}{2} \ \ frac{12}{13}* frac{14}{17}= frac{12*14}{13*17}= frac{168}{221} \ \ frac{17}{14}* frac{13}{24}= frac{17*13}{14*24}= frac{221}{336} \ \ frac{168}{221}* frac{221}{336}= frac{168*221}{221*336}= frac{37128}{74256}= frac{1*37128}{2*37128}= frac{1}{2}$

Answer 2

12/13*14/17*17/14*13/24=12/24=1/2
