Daca te referi sa simplific cele doua fractii zecimale :
1,1(3)=1 [tex] \frac{13-1}{90} [/tex] = 1 [tex] \frac{12}{90} [/tex] = [tex] \frac{1*12+90}{90} [/tex] = [tex] \frac{102}{90} [/tex] simplificata prin 2 = [tex] \frac{51}{45} [/tex]
2,07(27)=2 [tex] \frac{727-7}{990} [/tex] = 2 [tex] \frac{720}{990} [/tex] = [tex] \frac{2*720+990}{990} [/tex] = [tex] \frac{2430}{990} [/tex] simplificata prin 2 = [tex] \frac{1215}{495} [/tex] simplificata prin 5 = [tex] \frac{243}{99} [/tex] simplificata prin 3 = [tex] \frac{81}{33} [/tex] simplificata prin 3 = [tex] \frac{27}{11} [/tex]
Daca te referi sa calculez cele doua fractii zecimale :
1,1(3)-2,07(27)= -52,59
