Answer 1

$\dfrac{30}{100} \rightarrow \dfrac{3}{10}\\\\ \dfrac{8}{100} \rightarrow \dfrac{4}{50} \rightarrow \dfrac{2}{25}\\\\ \dfrac{124}{100} \rightarrow \dfrac{62}{50} \rightarrow \dfrac{31}{25}\\\\ \dfrac{0,4}{100} \rightarrow \dfrac{4}{1000} \rightarrow \dfrac{2}{500} \rightarrow \dfrac{1}{250}\\\\ \dfrac{5.000}{100} \rightarrow \dfrac{2.500}{50} \rightarrow \dfrac{1.250}{25} \rightarrow \dfrac{250}{5} \rightarrow \dfrac{50}{1} \rightarrow 50$
