Question

a+b+c=540 a=3xb c=b:2 (metoda grafica)

Answer 1

a+b+c = 540
a = 3×b
c = b :2 => b = 2×c
a |___|___|___|___|___|___|
b |___|___|
c |___|
avem 9 segmente egale = 540
540 : 9 = 60 (un segment egal)
a = 6×60 = 360
b = 2×60 = 120
c = 60

Verificare:
360+120+60 = 540

a = 360
b = 120
c = 60

Answer 2

A /........../.........../.........../......../........./......../
B /........../........../ } 540
C/.........../

540:9=60( nr c,respectiv un segment)
60•2=120( nr b)
60•6=360( nr a)

Verificarea: 360+120+60=540.

Succes!
