Question

a+b+c=250 a=(b:4)x2 c=(a:2):4 metoda grafica

Answer 1

a+b+c = 250
a = (b:4)×2
c= (a:2):4

a = 8 segmente egale
b = 16 segmente egale
c = 1 segment egale

avem 8+16+1 = = 25 segmente egale = 250
250 : 25 = 10 (un segment egal)
a = 8 × 10 = 80
b = 16 × 10 = 160
c = 10

Verificare:
80 + 160 +10 = 250
80 = 160:4×2
80 = 40×2
80=80

a = 80
b = 160
c = 10
