I'm confused about the numerators of each one. I'm not sure what values to use for the old axis. Can you possibly provide an example of how .38 can become 0 and .62 can become 1? I'd really love to understand this a bit better, thank you.
the formula I gave

X=\frac{x-a}{b-a}

in your question, a=.38, b=.62

hence formula for this question becomes

X=\frac{x-.38}{.62-.38}

X=\frac{x-.38}{.24}

if x=.38,X=\frac{.38-.38}{.24}...which is zero.

if x=.62,X=\frac{.62-.38}{.24}...which is one.
