Suma a trei numere a+b+c=1100.Știind ca a=3b si b=2c sa se afle cele trei numere.

Răspuns :

a+b+c=1100
a=3b
b=2c=>c=b;2
3b+b+b:2=1100amplificam
6b+2b+b=2200
10b=2200
b=2200:9
b=244,4
a=3x244,4=733,3
c=244,4:2=122,2

verificare 733,3+244,4+122,2=1100

a+b+c+1100
b=2c
c=b:2
a=3b
3b+b+b:2=1100
9b=2200
b=244,44
a=3*244,44=733,33
c=122,23.
