Answer 1

$100 - (4 frac{17}{24}cdot 0,225cdot 5,4 : 4,5 + 22 frac{5}{24}) = 76 frac{1249}{2400} \\ 1) ; 4 frac{17}{24}cdot 0,225 = frac{113}{24}cdot frac{9}{40} = frac{1017}{960} = frac{339}{320} \\ 2) ; frac{339}{320}cdot 5,4 =  frac{339}{320}cdot frac{27}{5} = frac{9153}{1600} \\ 3) ; frac{9153}{1600} : 4,5 = frac{9153}{1600} : frac{9}{2} = frac{9153}{1600}cdot frac{2}{9} = frac{1017}{800} \\ 4) ; frac{1017}{800} + frac{533}{24} = frac{3051+53300}{2400} = frac{56351}{2400} = 23 frac{1151}{2400} \\ 5) ; 100 - 23 frac{1151}{2400} = 99 frac{2400}{2400} - 23 frac{1151}{2400} = 76 frac{1249}{2400}$
