392.25 is what percent of 525 - 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 525 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 525, so we can write it down as 100%=525.
4. We know, that x% equals 392.25 of the output value, so we can write it down as x%=392.25.
5. Now we have two simple equations:
1) 100%=525
2) x%=392.25
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%=525/392.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 392.25 is what percent of 525

100%/x%=525/392.25
(100/x)*x=(525/392.25)*x       - we multiply both sides of the equation by x
100=1.3384321223709*x       - we divide both sides of the equation by (1.3384321223709) to get x
100/1.3384321223709=x
74.714285714286=x
x=74.714285714286

now we have:
392.25 is 74.714285714286% of 525
