Homework Statement
Real world use of (x-y)/(x+y).
Homework Equations
(x-y)/x
The Attempt at a Solution
(x-y)/x solves for the mean difference ratio. I had 400 oranges and sold 100. 400-100/400 gives .75 or 75% remaining. I do not understand where I would use the difference over sum equation. The answer: .6 or 60% using this equation baffles me.
Can anyone set me straight on this.
Thanks!
