equation for variable of which constant is percentage thereof

Question

algebraic equation for constant number that is a percentage or fraction of variable number and steps to solve

Answer 1

C=constant

V=variable

Arbitrarily, let's assign a value of 1/2 or 0.5 (however you want to notate 50%) for your percentage/fraction.

C=V/2

or C=0.5V

Isolate the variable to one side.  V=2C

Plug in whatever values you know (you should know the constant and the fraction).  Solve the equation.

I hope this is what you meant.
