Question

Aflati numerele naturale x,y,z stiind ca sunt direct proportionale cu 3, 5, 4, iar suma lor este 264.

Answer 1

===========================

Answer 2

$\frac{x}{3} = \frac{y}{5} = \frac{z}{4} = k$
$x + y + z = 264$
$x = 3k \\ y = 5k \\ z = 4k$

3k+5k+4k=264
12k=264
k=264/12
k=22

x=3k=3x22=66
y=5k=5x22=110
z=4k=4x22=88
