Помогите,пожалуйста!

Решите задачу:

$\frac{3}{5} = \frac{6}{10} = 0.6 \\ \frac{1}{4} = \frac{75}{100} = 0.75 \\ \frac{13}{20} = \frac{65}{100} = 0.65 \\ \frac{3}{25} = \frac{12}{100} = 0.12 \\ \frac{19}{40} = \frac{475}{1000} = 0.475 \\$
$\frac{103}{125} = \frac{824}{1000} = 0.824 \\ \frac{7}{250} = \frac{28}{1000} = 0.028 \\ \frac{492}{500} = \frac{984}{1000} = 0.984 \\ \frac{83}{400} = \frac{2075}{10000} = 0.2075 \\ \frac{1231}{2500} = \frac{351714}{1000000} = 0.351714$
