Question

impartiti numarul 2016 in parti direct proportionale cu numerele 3,15 si 24 NU MAI AM PUNCTE DAR DAU CORONITA SI EVALUARE DE 6 STELE !

Answer 1

a/3=b/15=c/24=k
a=3k
b=15k
c=24k
3k+15k+24k=2016
42k=2016 =>k=48
a=144
b=720
c=1152

Answer 2

{ a,b,c } d.p { 3,15,24 }
---------------------------/----------
a + b  + c = 2016
----------------------------//----------

a  / 3 = b / 15 = c / 24

a / 3 = K => a = 3 K
b / 15 = K => b = 15 K
c / 24 = K => c = 24 K

3 K + 15 K + 24 K = 2016

18 K + 24 K = 2016

42 K = 2016

K = 2016 : 42

K  = 48

a = 48 x 3 = 144

b = 48 x 15   = 720

c = 48 x 24  = 1152
