Vă rog vreau cu rationament pentu clasa a 3-a

Answer 1

a+b+c = 11
a:b = 3 => a = 3×b
a:c = 2 => c = a:2

a |__|__|__|__|__|__|
b |__|__|
c |__|__|__|

avem 11 segmente egale = 11
11 : 11 = 1 ( un segment)
a = 6×1 = 6
b = 2×1 = 2
c = 3×1 = 3

Verificare:
6+2+3 = 11

Numerele sunt:
6; 2 ; 3.

Answer 2

A+B+C=11
 A:B=3
 A:C=2         
B+C=2+3=5
(A+B+C)-B+C=11-5=6
A=6

6 : B=3
B=6 :3
B=2

6 :C=2
C=6 :2
C=3
