Question

transformati in fractii ordinare ireductibile :
0,5
1,25
3,2
0.(7)
0,(63)
0,2(63)
0,01(792)
1,2(6)

Answer 1

0,5 = $\frac{5}{10}= \frac{1}{2}$
1,25 = $\frac{125}{100}= \frac{25}{20}= \frac{5}{4}$
3,2 = $\frac{32}{10}= \frac{16}{5}$
0,(7) = $\frac{7}{9}$
0,(63) = $\frac{63}{99} = \frac{21}{33} = \frac{7}{11}$
0,2(63) = $\frac{263-2}{990} = \frac{261}{990} = \frac{87}{330}= \frac{29}{110}$
0,01(792) = [tex] \frac{1792-1}{99900} = \frac{1791}{99900} = \frac{199}{11100} [/tex]
1,2(6) = $\frac{126-12}{90} = \frac{114}{90} = \frac{19}{15}$
