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:

FAQ: Real World Applications of the (x-y)/(x+y) Equation

What is the "Difference over Sum Equation"?

The "Difference over Sum Equation" is a mathematical formula used to determine the difference between two values divided by their sum. It is represented as (a-b)/(a+b), where a and b are the two values being compared.

How is the "Difference over Sum Equation" used in science?

The "Difference over Sum Equation" is commonly used in science to calculate the relative difference between two values. It can be used to compare measurements, data sets, or experimental results.

What is the significance of the "Difference over Sum Equation" in scientific research?

The "Difference over Sum Equation" allows scientists to quantitatively analyze and compare data, which is crucial in conducting accurate and reliable research. It helps identify any significant differences between two values and can aid in drawing conclusions.

Are there any limitations to the "Difference over Sum Equation"?

Like any mathematical equation, the "Difference over Sum Equation" has its limitations. It is most effective when used with continuous data and may not be suitable for discrete or categorical data. Additionally, it does not take into account any other factors or variables that may influence the difference between two values.

Can the "Difference over Sum Equation" be used in other fields besides science?

Yes, the "Difference over Sum Equation" can be applied in various fields such as economics, finance, and statistics. It is a versatile formula that can be used to compare and analyze data in any field that involves numerical values.
