Answer 2

Question :

If n/(n+15) = 4/9 then n=?

Answer :

The value of n is 12.

Given :

The equation n/(n+15) = 4/9

To find :

The value of n

Solution :

According to the equation :

n/(n+15) = 4/9

Cross multiplying, we get :

9n = 4(n+15)

=> 9n = 4n + 60

=> 9n - 4n = 60

=> 5n = 60

=> n = 60/5

=> n = 12

Hence, the value of n is 12.
