Question

Calculati:
2,3(4):1,1(1)+0,89 (as-i dori sa-mi explicati cum ati facut)

Answer 1

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