Question

If x/y=9 then (x-y) /(x+y)

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

(x - y) / (x + y) = 4 / 5

Step-by-step explanation:

Solution:

we are given that

         x / y = 9  

  ⇒          x = 9y

we are required:

(x - y) / (x + y) = ?    

Now putting value of " x = 9y "

(x - y) / (x + y) = (9y - y) / (9y + y)

                       = 8y / 10y

By reducing the fraction to its lowest form

(x - y) / (x + y) = 4 / 5

So

(x - y) / (x + y) = 4 / 5
