Answer 1

Explicație pas cu pas:

1.

$0.3 = \frac{3}{10}$

$0.31 = \frac{31}{100}$

$0.6 = \frac{6}{10} = \frac{3}{5}$

$12.5 = \frac{125}{10} = \frac{25}{2}$

$2.512 = \frac{2512}{1000} = \frac{314}{125}$

2.

$0.(4) = \frac{4}{9}$

$0.(47) = \frac{47}{99}$

$1.(6) = \frac{16 - 1}{9} = \frac{15}{9} = \frac{5}{3}$

$12.(5) = \frac{125 - 12}{9} = \frac{113}{9}$

$2.(512) = \frac{2512 - 2}{999} = \frac{2510}{999}$

3.

$0.8(5) = \frac{85 - 8}{90} = \frac{77}{90}$

$0.7(31) = \frac{731 - 7}{990} = \frac{724}{990} = \frac{362}{495}$

$1.2(6) = \frac{126 - 12}{90} = \frac{114}{90} = \frac{57}{45}$

$2.4(512) = \frac{24512 - 24}{9990} = \frac{24488}{9990} = \frac{12244}{4995}$
