Answer 1

$frac{5,3:2,4-1 frac{1}{12}}{0,702:1,3-0,415}=0,9$
1) 5,3:2,4=$frac{53}{10}: frac{24}{10}=frac{53}{10}*frac{10}{24} = frac{53}{24}=2 frac{5}{24}$
2) $2 frac{5}{24}-1 frac{1}{12}=2 frac{5}{24}-1 frac{2}{24}= 1frac{3}{24}=1frac{1}{8}$
3) 0,702:1,3=0,54
4) 0,54-0,415=0,125
5) $1 frac{1}{8}:0,125= frac{9}{8}: frac{125}{100}=frac{9}{8}:frac{5}{4}=frac{9}{8}* frac{4}{5}= frac{9}{2*5}=frac{9}{10}=0,9$
