Question

Fine the ratio of (4x-5y) and (5x+2y)bif (2y-y):(2x+4y) = 1:4

Answer 1

Answer:

1:26

Step-by-step explanation:

2x-y/2x+4y=1/4

2x-y/x+2y=1/2

4x-2y=x+2y

3x=4y

x/y=4/3

Now  

4x-5y/5x+2y=

Divide numerator and denominator by y

(4x/y-5) /(5x/y+2)  

Using x/y=4/3 here we get

(16/3-5)/(20/3+2)  

(1/3) /(26/3)  

1/26
