4x-3y=0,则（x-y)/y=
4x-3y=0,则（x-y)/y=

4x-3y=0,则（x-y)/y=
x/y=3/4
(x-y)/y=x/y-1=3/4-1=-1/4

4x-3y=0
4x=3y
x/y=3/4
（x-y)/y
=x/y-1
=3/4-1
=-1/4

4x-3y=0
4x=3y
设x=3k y=4k
(x-y)/y=(3k-4k)/4k=-1/4

4x-3y=0
x=3/4y
（x-y)/y=(3/4y-y)/y=-1/4

因为4x-3y=0，得出x/y=3/4
（x-y)/y= x/y - 1 =3/4 - 1 =-1/4

负四分之一

4x-3y=0,则 4x=3y x=3/4*y
（x-y)/y= (3/4 Y -y)/y
=-1/4 Y /y
= - 1/4
