x / 0,1 = y / ( 2 / 5 ) = z / ( 1 / 3 ) ;
x + y + z = 1;
Prima relatie este echivalenta cu x / ( 1 / 10 ) = y / ( 2 / 5 ) = z / ( 1 / 3 ) = ( x+ y + z ) / ( 1 / 10 + 2 / 5 + 1 / 3 ) = 1 / ( 25 / 30 ) = 30 / 25 = 6 / 5 ;
Atunci x = ( 6 / 5 ) × ( 1 / 10 ) => x = 6 / 50 = 0,12 ;
Analog, y = 0,48 si z = 3,60 ;
Bafta !
