Answer 2

Answer:

$\frac{x+y}{x-y}= -\frac{5}{3}$

Step-by-step explanation:

Given,

1.6 x = 0.4 y

To find,

$\frac{x+y}{x-y}$.....(1)

Considering,

1.6 x = 0.4 y... (2)

We can write equation (2) as

$y = \frac{1.6}{0.4} x$

⇒ y = 4x....(3)

Substituting equation (3) in (1)

we get:

$\frac{x+y}{x-y} = \frac{x+4x}{x-4x}$

$\frac{x+y}{x-y} = \frac{5x}{-3x}$

Therefore,

$\frac{x+y}{x-y}= -\frac{5}{3}$
