550.3 is what percent of 18120.3 - 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 18120.3 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 18120.3, so we can write it down as 100%=18120.3.
4. We know, that x% equals 550.3 of the output value, so we can write it down as x%=550.3.
5. Now we have two simple equations:
1) 100%=18120.3
2) x%=550.3
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%=18120.3/550.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 550.3 is what percent of 18120.3

100%/x%=18120.3/550.3
(100/x)*x=(18120.3/550.3)*x       - we multiply both sides of the equation by x
100=32.928039251317*x       - we divide both sides of the equation by (32.928039251317) to get x
100/32.928039251317=x
3.0369254372168=x
x=3.0369254372168

now we have:
550.3 is 3.0369254372168% of 18120.3
