a-c=39
b:c=2

Answer 1

a:b = 2 => a =2×bb: c = 2 => b = 2×ca-c = 39
a |____|____|____|____|b |____|____|c |____|4 segmente egale - 1 segment egal = 3 segmente egale = 3939 : 3 = 13 ( un segment)a = 4×13 = 52b = 2×13 = 26c = 13
Verificare:52-13 = 39
a = 52b = 26c = 13

Answer 2

a:b=2 rezulta ca a=2x bb :c=2 rezulta ca b=2xCA -C=39
4 segmente egale-1 segmente egale=3segmente egale =3939:3=13 un segment a = 4x13=52b=2x13=26c=13
a=52 b =26 c=13
