52.1 is what percent of 864 - 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 864 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 864, so we can write it down as 100%=864.
4. We know, that x% equals 52.1 of the output value, so we can write it down as x%=52.1.
5. Now we have two simple equations:
1) 100%=864
2) x%=52.1
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%=864/52.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.1 is what percent of 864

100%/x%=864/52.1
(100/x)*x=(864/52.1)*x       - we multiply both sides of the equation by x
100=16.58349328215*x       - we divide both sides of the equation by (16.58349328215) to get x
100/16.58349328215=x
6.0300925925926=x
x=6.0300925925926

now we have:
52.1 is 6.0300925925926% of 864
