5.28 is what percent of 12.18 - 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 12.18 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 12.18, so we can write it down as 100%=12.18.
4. We know, that x% equals 5.28 of the output value, so we can write it down as x%=5.28.
5. Now we have two simple equations:
1) 100%=12.18
2) x%=5.28
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%=12.18/5.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.28 is what percent of 12.18

100%/x%=12.18/5.28
(100/x)*x=(12.18/5.28)*x       - we multiply both sides of the equation by x
100=2.3068181818182*x       - we divide both sides of the equation by (2.3068181818182) to get x
100/2.3068181818182=x
43.349753694581=x
x=43.349753694581

now we have:
5.28 is 43.349753694581% of 12.18
