102.17 is what percent of 549 - 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 549 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 549, so we can write it down as 100%=549.
4. We know, that x% equals 102.17 of the output value, so we can write it down as x%=102.17.
5. Now we have two simple equations:
1) 100%=549
2) x%=102.17
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%=549/102.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 102.17 is what percent of 549

100%/x%=549/102.17
(100/x)*x=(549/102.17)*x       - we multiply both sides of the equation by x
100=5.3733972790447*x       - we divide both sides of the equation by (5.3733972790447) to get x
100/5.3733972790447=x
18.610200364299=x
x=18.610200364299

now we have:
102.17 is 18.610200364299% of 549
