Question

Raportul numerelor x si y este 2pe 3
Aflati xpe 4y= si x+y pe x=

Answer 1

x/y=2/3 =>x=2y/3
2y/3 : 4y =
2y/3 • 1/4y =
1/6

(2y/3 + y) : 2y/3 =
5y/3 • 3/2y =
5/2

Answer 2

x/y=2/3, amplificam fractia 2/3 cu "a"=>
=> x/y=2a/3a=> x=2a
y=3a

x/4y= 2a/4×(3a)= 2a/12×4a, se simplifica "a" =>
x/4y= 2/12, se simplifica prin 2=> x/4y=1/6

x+y/x= 2a+3a/2a= 5a/2a, se simplifica "a"=>
x+y/x=5/2
