Запишем дроби в виде десятичных

1. a) $$\frac{3}{5} = \frac{3 \cdot 2}{5 \cdot 2} = \frac{6}{10} = 0.6$$
2. б) $$\frac{7}{25} = \frac{7 \cdot 4}{25 \cdot 4} = \frac{28}{100} = 0.28$$
3. в) $$\frac{3}{4} = \frac{3 \cdot 25}{4 \cdot 25} = \frac{75}{100} = 0.75$$
4. г) $$\frac{27}{50} = \frac{27 \cdot 2}{50 \cdot 2} = \frac{54}{100} = 0.54$$
5. д) $$\frac{13}{20} = \frac{13 \cdot 5}{20 \cdot 5} = \frac{65}{100} = 0.65$$
6. e) $$\frac{5}{8} = \frac{5 \cdot 125}{8 \cdot 125} = \frac{625}{1000} = 0.625$$
