Question

suma a trei numere este 234,36 aflati cele trei numere stiind ca primul este de doua ori mai mic decat al doilea si de trei ori mai mic decat al treilea

Answer 1

a+b+c=234,36
a=b:2 ⇒ b=2a
a=c:3 ⇒ c=3a
a+2a+3a=234,56
6a=234,56
a=234,56:6
a=39,09(3)
b=39,09(3) x 2=78,18(6)
c=39,09(3) x 3=117,28

Answer 2

a+b+c=234,36
a=b:2
a=c:3
b=2a
c=3a

a+2a+3a=234,36
6a=234,36
a=234,36:6
a=39,06

b=2x39,06
b=78,12
c=3x39,06
c=117,18

Verificare:
a+b+c=234,36
39,06+78,12+117,18=234,36
