Answer 1

a) 0,(18)=$\frac{18}{99}$
b)3,(2)=$\frac{32-2}{9} = \frac{30}{9} = \frac{10}{3}$
c) 6,1(8)=$\frac{618-61}{90} = \frac{557}{90}$
d) 5,12(18)=$\frac{51218-512}{9900} = \frac{50706}{9900} = \frac{25353}{4950} mai simplifici si tu$
e) 25,1(378)=$\frac{251378-251}{9990} = \frac{251127}{9990}$ si aici mai simplifici pana ajungi la o fractie ireductibila
