18.71 is what percent of 100 - 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 100 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 100, so we can write it down as 100%=100.
4. We know, that x% equals 18.71 of the output value, so we can write it down as x%=18.71.
5. Now we have two simple equations:
1) 100%=100
2) x%=18.71
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%=100/18.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.71 is what percent of 100

100%/x%=100/18.71
(100/x)*x=(100/18.71)*x       - we multiply both sides of the equation by x
100=5.3447354355959*x       - we divide both sides of the equation by (5.3447354355959) to get x
100/5.3447354355959=x
18.71=x
x=18.71

now we have:
18.71 is 18.71% of 100
