131.8 is what percent of 204 - 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 204 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 204, so we can write it down as 100%=204.
4. We know, that x% equals 131.8 of the output value, so we can write it down as x%=131.8.
5. Now we have two simple equations:
1) 100%=204
2) x%=131.8
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%=204/131.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 131.8 is what percent of 204

100%/x%=204/131.8
(100/x)*x=(204/131.8)*x       - we multiply both sides of the equation by x
100=1.5477996965099*x       - we divide both sides of the equation by (1.5477996965099) to get x
100/1.5477996965099=x
64.607843137255=x
x=64.607843137255

now we have:
131.8 is 64.607843137255% of 204
