64.97 is what percent of 318.83 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 318.83 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 318.83, so we can write it down as 100%=318.83.
4. We know, that x% equals 64.97 of the output value, so we can write it down as x%=64.97.
5. Now we have two simple equations:
1) 100%=318.83
2) x%=64.97
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=318.83/64.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.97 is what percent of 318.83

100%/x%=318.83/64.97
(100/x)*x=(318.83/64.97)*x       - we multiply both sides of the equation by x
100=4.9073418500847*x       - we divide both sides of the equation by (4.9073418500847) to get x
100/4.9073418500847=x
20.377630712292=x
x=20.377630712292

now we have:
64.97 is 20.377630712292% of 318.83
