Fie x,y,z numerele.
y=x/3
z=2x
x+y+z=340=> x+x/3+2x=340 |*3 => 3x+x+6x= 1020=> 10x=1020=> x=102
y=102/3=34
z=204

A.I____I____I____I
b.I____I
c.I____I____I____I____I____I____I 

 Suma este 340. Avem 10 parti egale deci aflam o parte :
  340:10=34 ( nr. b )
  34x3=102 ( nr. a )
  34x6=204 ( nr. c )

Verificare : 102+34+204=340
