camelia si Adriana au sume diferite de lei.Daca impartim suma cameliei la suma adrianei obtinem 3,iar daca scadem din suma adrianei obtinem 54.cati lei are fiecare ?metoda grafica

Answer 1

C - A = 54 lei
C : A = 3 => C = 3×A
C |____|____|____|
A |____|
3 segmente egale - 1 segment egal = 2 segmente egale = 54
54 : 2 = 27 (un segment egal)
C = 3 × 27 = 81
A = 27

Verificare:
81 - 27 = 54
81 : 27 = 3

81 lei are Camelia
27 lei are Adriana
