Getting the percentage of a number between 2 other numbers

[Galicate (Gal)]

I have 3 numbers, a Min ( 18 ), a Max ( 24 ), and a variable in-between ( Let’s say 21 ).

How do I get the percentage of how far along the variable is between those two numbers?
At 21 it’s 50% but I don’t know how to calculate it.

[ConnectNot_connect]

for simple terms,
you can calculate the difference between max and min, then max - (wanted value) = 2ndDiff, and simply

(2ndDiff / maxMinDiff) * 100 = 50%

24 - 18 = 6
24 - 21 = 3
3 / 6 = 0.5, * 100 = 50

function calculatePercentage(min, max, var)
	local distance = max - min
	local progress = var - min
	local percentage = (progress / distance) * 100
	return percentage
end
