102.5 is what percent of 3540 - 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 3540 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 3540, so we can write it down as 100%=3540.
4. We know, that x% equals 102.5 of the output value, so we can write it down as x%=102.5.
5. Now we have two simple equations:
1) 100%=3540
2) x%=102.5
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%=3540/102.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 102.5 is what percent of 3540

100%/x%=3540/102.5
(100/x)*x=(3540/102.5)*x       - we multiply both sides of the equation by x
100=34.536585365854*x       - we divide both sides of the equation by (34.536585365854) to get x
100/34.536585365854=x
2.8954802259887=x
x=2.8954802259887

now we have:
102.5 is 2.8954802259887% of 3540
