- question is wrong!!!
- 13 years agoHelpfull: Yes(10) No(1)
- 2x/5y=5x/3y
=>5x/3y-2x/5y=0
=>x/y(5/3-2/5)=0
x/y(19/15)=0
x/y=0 - 12 years agoHelpfull: Yes(7) No(0)
- Given: 3X/5Y=5Y/3X..
SO X/Y IS:5/3
sol:cross mul ie,9x^2=25y^2
x^2/y^2=(25/9)
x/y=5/3 - 13 years agoHelpfull: Yes(2) No(25)
- (2/5-5/3)x/y=0
(6-25/15)x/y=0
x/y=15/19 - 12 years agoHelpfull: Yes(2) No(18)
- divide Nr & Dr by y...
2(x/y)/5=5(x/y)/3
cross-multiply...
6(x/y)=25(x/y)
hence,19(x/y)=1
(x/y)=1/19 - 12 years agoHelpfull: Yes(1) No(5)
- plz explain clearly

- give: 2x/5y=5x/3y
=> (2x - 5y)/5y = (5x - 3y)/3y
=>(2x - 5y)/5 = (5x - 3y)/3 [ as y!=0]
=> 6x-15y = 25x - 15y
=> - 19x = - 30y
=> x/y = 30/19 - 9 years agoHelpfull: Yes(0) No(2)
- sorry i'm doing wrong calculation... there have no ratio between x and y because after calculating we get 6x=25x ( which is not possible).
