31.68 is what percent of 204.54 - 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 204.54 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 204.54, so we can write it down as 100%=204.54.
4. We know, that x% equals 31.68 of the output value, so we can write it down as x%=31.68.
5. Now we have two simple equations:
1) 100%=204.54
2) x%=31.68
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%=204.54/31.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.68 is what percent of 204.54

100%/x%=204.54/31.68
(100/x)*x=(204.54/31.68)*x       - we multiply both sides of the equation by x
100=6.4564393939394*x       - we divide both sides of the equation by (6.4564393939394) to get x
100/6.4564393939394=x
15.488413024347=x
x=15.488413024347

now we have:
31.68 is 15.488413024347% of 204.54
