transformam in fractii ordinare:
2,3(4)=[tex] \frac{234-23}{90} [/tex]=[tex] \frac{211}{90} [/tex]
1,1(1)=[tex] \frac{111-11}{90} [/tex]=[tex] \frac{100}{90} [/tex]
[tex] \frac{211}{90}: \frac{100}{90} = \frac{211}{90} * \frac{90}{100}
[/tex]
simplificam in diagonala si avem
[tex] \frac{211}{1} * \frac{1}{100} = \frac{211}{100} [/tex]
2,11+0,89=3
sper ca te-am ajutat ! ;)
