Question

Suma a trei numere consecutive este 36.Care sunt numerele?

Answer 1

a-1+a+a+1=36
3a=36
a=12
11,12,13

Answer 2

a |------| } 36

b |------|-1-|

c |------|--2--|

36 - ( 1 + 2 ) = 36 - 3 = 33 ( 3 segmente egale )

33 : 3 = 11 ( un segment )

a = 11

b = 12

c = 13

________________

a + a + 1 + a + 2 = 36

3a = 36 - ( 1 + 2 )

3a = 36 - 3

3a = 33

a = 33 : 3

a = 11

Numerele sunt :

→ 11 ; 12 ; 13

Succes,Liana!
