In summary, the conversation discusses finding a number that is a certain percentage between two given numbers. The formula used is (x1 + x2) / 2 for 50% and then (x1 + x_p) / 2 for 75%. However, this formula only works for certain percentages and may not be efficient. A better formula is x_p = x1 + p(x2 - x1), where p represents the desired percentage. This formula can be used to find any percentage between two given numbers.

Hey, So I need to know what number is 75% between 2 lines? Line 1 = 124.464 and Line 2 = 124.444. Currently I use
Line 1 + Line 2 / 2 = 50% or (124.454) Then (124.454 + Line 1) / 2 = 75% or (124.459). Is there a easier or better way to get these results, cause this formula can't get percents like 60% or 40%.
PS: Wasn't sure what topic to put this under, first time here.
Thank you for your time and help!

Suppose you have two real numbers \(x_1\) and \(x_2\) with \(x_1<x_2\). And we want to find a third number \(x_p\) that is a part \(p\) (where \(0\le p\le1\)) of the distance from \(x_1\) to \(x_2\). Then I would use:

\(\displaystyle x_p=x_1+p(x_2-x_1)\)

Does that make sense?

Yes! Thats exactly what I needed! Thank you so much! I’ve been out of school for too many years now. Haha.
 

FAQ: Percentage between two numbers
