{a,b,c} direct proportionale {1; 2/3; 2} => a/1=b/2/3=c/2=>K
A=1K
b=2/3K
c=2K
1K+2/3K+3K=66
Aducem la acelasi numitor si vine: 3K/3+2K/3+6K/3=66
Adunam tot si vine: 11K/3=66
11K=66*3=> 11K = 198 => K=198:11=18
K=18
Si acum aflam numerele
A=1K=1*18=18
B=2/3K=2/3*18=36/3=12
C=2K-=2*18=36
Proba: 18+12+36=66
Sper ca te-am ajutat!
