Question

Сократите дроби и запиши их в виде десятичных дробей: 20\25
17\34
24\32
39\60
27\75
6\24

Answer 1

$\frac{20}{25} = \frac{20 \div 5}{25 \div 5} = \frac{4}{5} = 0.8 \\ \\ \frac{17}{34} = \frac{17 \div 17}{34 \div 17} = \frac{1}{2} = 0.5 \\ \\ \frac{24}{32} = \frac{24 \div 8}{32 \div 8} = \frac{3}{4} = 0.75 \\ \\ \frac{39}{60} = \frac{39 \div 3}{60 \div 3} = \frac{13}{20} = 0.65 \\ \\ \frac{27}{75} = \frac{27 \div 3}{75 \div 3} = \frac{9}{25} = 0.36 \\ \\ \frac{6}{24} = \frac{6 \div 6}{24 \div 6} = \frac{1}{4} = 0.25$
