63.81 is what percent of 391.41 - 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 391.41 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 391.41, so we can write it down as 100%=391.41.
4. We know, that x% equals 63.81 of the output value, so we can write it down as x%=63.81.
5. Now we have two simple equations:
1) 100%=391.41
2) x%=63.81
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%=391.41/63.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63.81 is what percent of 391.41

100%/x%=391.41/63.81
(100/x)*x=(391.41/63.81)*x       - we multiply both sides of the equation by x
100=6.1339915373766*x       - we divide both sides of the equation by (6.1339915373766) to get x
100/6.1339915373766=x
16.302598298459=x
x=16.302598298459

now we have:
