SUMMARY

The discussion centers on the real-world applications of the equation (x-y)/(x+y), which calculates the balance between two quantities. A user illustrates its use by comparing the number of oranges sold to the total, resulting in a 75% remaining calculation. The confusion arises when applying the difference over sum equation, yielding a 60% result in another example involving a party with 70 girls and 62 boys. The equation effectively indicates the level of imbalance between two groups.

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!

you have a party with 70 girls and 62 boys …

(x-y)/(x+y) tells you how unbalanced it is :wink:
 
Thanks, that was exactly what I was needing to know.
