18.64 is what percent of 200 - 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 200 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 200, so we can write it down as 100%=200.
4. We know, that x% equals 18.64 of the output value, so we can write it down as x%=18.64.
5. Now we have two simple equations:
1) 100%=200
2) x%=18.64
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%=200/18.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.64 is what percent of 200

100%/x%=200/18.64
(100/x)*x=(200/18.64)*x       - we multiply both sides of the equation by x
100=10.729613733906*x       - we divide both sides of the equation by (10.729613733906) to get x
100/10.729613733906=x
9.32=x
x=9.32

now we have:
18.64 is 9.32% of 200
