18.2 is what percent of 81.6 - 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 81.6 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 81.6, so we can write it down as 100%=81.6.
4. We know, that x% equals 18.2 of the output value, so we can write it down as x%=18.2.
5. Now we have two simple equations:
1) 100%=81.6
2) x%=18.2
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%=81.6/18.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.2 is what percent of 81.6

100%/x%=81.6/18.2
(100/x)*x=(81.6/18.2)*x       - we multiply both sides of the equation by x
100=4.4835164835165*x       - we divide both sides of the equation by (4.4835164835165) to get x
100/4.4835164835165=x
22.303921568627=x
x=22.303921568627

now we have:
18.2 is 22.303921568627% of 81.6
