528.49 is what percent of 4125 - 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 4125 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 4125, so we can write it down as 100%=4125.
4. We know, that x% equals 528.49 of the output value, so we can write it down as x%=528.49.
5. Now we have two simple equations:
1) 100%=4125
2) x%=528.49
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%=4125/528.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 528.49 is what percent of 4125

100%/x%=4125/528.49
(100/x)*x=(4125/528.49)*x       - we multiply both sides of the equation by x
100=7.8052564854586*x       - we divide both sides of the equation by (7.8052564854586) to get x
100/7.8052564854586=x
12.811878787879=x
x=12.811878787879

now we have:
