Question

transformati in fractii 1.1(3)-2.07(27)

Answer 1

Daca te referi sa simplific cele doua fractii zecimale :

1,1(3)=1 $\frac{13-1}{90}$ =  1 $\frac{12}{90}$ = $\frac{1*12+90}{90}$ = $\frac{102}{90}$ simplificata prin 2 = $\frac{51}{45}$ 

2,07(27)=2 $\frac{727-7}{990}$ = 2 $\frac{720}{990}$ = $\frac{2*720+990}{990}$ = $\frac{2430}{990}$ simplificata prin 2 = $\frac{1215}{495}$ simplificata prin 5 = $\frac{243}{99}$ simplificata prin 3 = $\frac{81}{33}$ simplificata prin 3 = $\frac{27}{11}$ 

Daca te referi sa calculez cele doua fractii zecimale : 
1,1(3)-2,07(27)= -52,59
