Answer 1

Răspuns:

$0.33 = \frac{33}{100}$

$2(6) = \frac{26 - 2}{9} = \frac{24}{9}$

$0(3) = \frac{3}{9}$

$1.6 = \frac{16}{10}$

$1.067 = \frac{1067}{1000}$

$2.(34) = \frac{232}{99}$

$2.345 = \frac{2345}{1000}$

$1.5 = \frac{15}{10}$

$1.9(6) = \frac{177}{90}$

Answer 2

Răspuns:

0.33=33/100

2(6) =(26-2)/9 = 24/9 = 8/3

0(3)=3/9=1/3

1,6=16/10=8/5

1,067=1067/1000

2,(34)=(234-2)/99=232/99

2,345=2345/1000=469/200

1,5=15/10=3/2

1,9(6)=(196-19)/90=177/90=59/30
