325.16 is what percent of 397 - 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 397 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 397, so we can write it down as 100%=397.
4. We know, that x% equals 325.16 of the output value, so we can write it down as x%=325.16.
5. Now we have two simple equations:
1) 100%=397
2) x%=325.16
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%=397/325.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 325.16 is what percent of 397

100%/x%=397/325.16
(100/x)*x=(397/325.16)*x       - we multiply both sides of the equation by x
100=1.2209373846722*x       - we divide both sides of the equation by (1.2209373846722) to get x
100/1.2209373846722=x
81.904282115869=x
x=81.904282115869

now we have:
325.16 is 81.904282115869% of 397
