How to determine Percent of a range?

Question

I have a range and a target. I want to determine that target is how percent of range.

for exam:

Minimum = -54
Maximum = 96
Target = -19.5

Result = 23%

The result (-19.5) is 23% of the range (-54 .. 96).

How can I calculate it?

Answer 1

The result can be obtained by

$$\dfrac{-19.5-(-54)}{96-(-54)} = .23$$

$$\dfrac{x_{target}-x_{mn}}{x_{max}-x_{min}}$$
