39.81 is what percent of 185 - 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 185 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 185, so we can write it down as 100%=185.
4. We know, that x% equals 39.81 of the output value, so we can write it down as x%=39.81.
5. Now we have two simple equations:
1) 100%=185
2) x%=39.81
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%=185/39.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.81 is what percent of 185

100%/x%=185/39.81
(100/x)*x=(185/39.81)*x       - we multiply both sides of the equation by x
100=4.6470735995981*x       - we divide both sides of the equation by (4.6470735995981) to get x
100/4.6470735995981=x
21.518918918919=x
x=21.518918918919

now we have:
39.81 is 21.518918918919% of 185
