512.71 is what percent of 668 - 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 668 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 668, so we can write it down as 100%=668.
4. We know, that x% equals 512.71 of the output value, so we can write it down as x%=512.71.
5. Now we have two simple equations:
1) 100%=668
2) x%=512.71
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%=668/512.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 512.71 is what percent of 668

100%/x%=668/512.71
(100/x)*x=(668/512.71)*x       - we multiply both sides of the equation by x
100=1.3028807708061*x       - we divide both sides of the equation by (1.3028807708061) to get x
100/1.3028807708061=x
76.752994011976=x
x=76.752994011976

now we have:
512.71 is 76.752994011976% of 668
