Answer 1

$frac{2,4*12,6*3,5}{6,3*4,8*31,5} = frac{6,3*3,5}{2,4*31,5} = frac{63*35}{24*315} = frac{63}{24*9} = frac{7}{24}$

$frac{1,7*4,92*7,2}{4,8*0,82*5,1} = frac{17*492*72}{48*82*51} = frac{17*6*72}{48*51} = frac{17*9}{51} = 3$

$frac{8,4*2 frac{1}{2}*12,1}{1,25*4*1,1} = frac{84*25*121}{125*4*11} =frac{21*11}{5} =frac{21*11}{5} =46,2$
