How to know the variable percentage between two numbers?

Question

1024 -----> 100%

940 -----> x%

800 -----> 0%

So (x) what percentage is it?

I appreciate the help!

Answer 1

Without getting into the context, and assuming a linear relationship then $y = 2.24x + 800$

$940 = 2.24x + 800$

$140 = 2.24x$

$x = 62.5\%$

Answer 2

800 is $0\%$ ? It does not seem interesting here. To calculate $x$ you just have to calculate the ratio : $$ \frac{940}{1024} $$ which is around $91.8\%$. Don't hesitate to go there : https://en.wikipedia.org/wiki/Percentage to understand more about percentages.
