4 is what percent of 18.27 - 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 18.27 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 18.27, so we can write it down as 100%=18.27.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=18.27
2) x%=4
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%=18.27/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 18.27

100%/x%=18.27/4
(100/x)*x=(18.27/4)*x       - we multiply both sides of the equation by x
100=4.5675*x       - we divide both sides of the equation by (4.5675) to get x
100/4.5675=x
21.893814997263=x
x=21.893814997263

now we have:
4 is 21.893814997263% of 18.27
