Question

Transformati in fracții ordinare ireductibile: 0,(7) 0,(63) 1,2(6) 0,01(792)

Answer 1

$0.(7) = \frac{7}{9}$

$0.(63) = \frac{63}{99} = \frac{21}{33} = \frac{7}{11}$

$1.2(6) = \frac{126 - 12}{90} = \frac{114}{90}=\frac{57}{45}=\frac{19}{15}$

$0.01(792) = \frac{1792 - 1}{99900} = \frac{1791}{99900} = \frac{597}{33300} = \frac{199}{11100}$

Answer 2

0,(7)=7/9,0,(63)=63/99=21/33=7/11;1,2(6)=126-12/90=114/90=19/15;0,01(792)=1792-1/99900=1791/99900=199/1110
