a+b+c =55
a |___|
b |___|___|
c |___|___|+15 } 55
5p+15=55
5p=55-15
5p=40
p=40÷5
p=8 (a)
8×2=16(b)
(8×2)+15=16+15=31 (c)
verificare
8+16+31=55
nr sunt 8 ,16 si 31
a |---------|
b |---------|---------| } 55.
c |---------|---------|-15-|
55 - 15 - 40 ( 5 segmente egale cu a)
40 : 5 = 8 (a)
8×2=16 ( b)
16 +15 = 31 (c)
Verificare: 8 + 16 + 31 = 55.
