Metoda figurativa,
a + b + c = 48
a = 2b
c = a + b
a |---|---|
b |---|
c |---|---|---| } 48
3 + 2 + 1 = 6 ( segmente egale )
48 : 6 = 8 ( b )
8 × 2 = 16 ( a )
8 × 3 = 21 ( c )
a + b + c = 48
a = 2b
c = a + b
a |---|---|
b |---|
c |---|---|---| } 48
3 + 2 + 1 = 6 ( segmente egale )
48 : 6 = 8 ( b )
8 × 2 = 16 ( a )
8 × 3 = 21 ( c )
