$frac{ frac{7}{24} : frac{5}{4} + frac{7}{2} }{ frac{2}{3} - frac{1}{4} } = frac{ frac{7}{24}*frac{4}{5} + frac{7}{2} }{ frac{4}{12} - frac{3}{12} }= frac{ frac{7}{6} *frac{1}{5} + frac{7}{2} }{ frac{1}{12}}= frac{ frac{7}{30} + frac{7}{2} }{ frac{1}{12} }= frac{ frac{105}{30} }{ frac{1}{12} }= frac{ frac{56}{15} }{ frac{1}{12} }= frac{56}{15} : frac{1}{12} = frac{56}{15} * frac{12}{1}$

1) $frac{7}{24} :0,125 = frac{7}{24}: frac{1}{8}= frac{7}{24} * frac{8}{1}= frac{7}{3}$
2) $frac{7}{3}+3,5 = frac{7}{3} + frac{7}{2}= frac{14+21}{6} = frac{35}{6}$
3) $frac{2}{3} -0,25= frac{2}{3} - frac{1}{4} = frac{8 - 3}{12}= frac{5}{12}$
4) $frac{35}{6} : frac{5}{12}= frac{35}{6} * frac{12}{5}= 7 * 2 = 14$
