80=2/3*R₃ => R₃=80*3 :2=240:2=120
d=1/3 *R₃ = 120:3=40 d=40 martisoare
c=1/4*R₂ R₂=c+R₃ R₂-R₂/4=120 aducem la acelasi numitor
3R₂=120 *4 => R₂=120*4:3=40*4=160 R₂=160
c=160:4 =40 c=40 martisoare
160 =2R₁/3 => R₁= 160*3 /2=480:2=240
b=R₁:3= 240 :3=80 b=80 martisoare
240=2t/3 t=240*3/2= 720:2= 360 total= 360 martisoare
a= 360 :3= 120 a= 120 martisoare
Verif : 120 +80+40 +40 +80 = 360 martisoare
