Помогите пожалуйста номер 738 если вы добрые .

738.
$1) \frac{1}{2} = \frac{5}{10} = 0.5 \\ \frac{2}{5} = \frac{4}{10} = 0.4 \: \: \: \ \frac{7}{5} = \frac{14}{10} = 1.4$
$\frac{4}{5} = \frac{8}{10} = 0.8$
$2) \frac{1}{4} = \frac{25}{100} = 0.25 \\ \frac{3}{20} = \frac{15}{100} = 0.15$
$\frac{8}{25} = \frac{32}{100} = 0.32 \\ \frac{7}{25} = \frac{28}{100} = 0.28$
$\frac{1}{50} = \frac{2}{100} = 0.02$
3)
$\frac{6}{125} = \frac{48}{1000} = 0.048 \\ \frac{3}{250} = \frac{12}{1000} = 0.012$
$\frac{7}{200} = \frac{35}{1000} = 0.035 \\ \frac{9}{500} = \frac{18}{1000} = 0.018$
