31.25 is what percent of 512.75 - 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 512.75 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 512.75, so we can write it down as 100%=512.75.
4. We know, that x% equals 31.25 of the output value, so we can write it down as x%=31.25.
5. Now we have two simple equations:
1) 100%=512.75
2) x%=31.25
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%=512.75/31.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.25 is what percent of 512.75

100%/x%=512.75/31.25
(100/x)*x=(512.75/31.25)*x       - we multiply both sides of the equation by x
100=16.408*x       - we divide both sides of the equation by (16.408) to get x
100/16.408=x
6.0945880058508=x
x=6.0945880058508

now we have:
31.25 is 6.0945880058508% of 512.75
