18.87 is what percent of 11 - 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 11 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 11, so we can write it down as 100%=11.
4. We know, that x% equals 18.87 of the output value, so we can write it down as x%=18.87.
5. Now we have two simple equations:
1) 100%=11
2) x%=18.87
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%=11/18.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.87 is what percent of 11

100%/x%=11/18.87
(100/x)*x=(11/18.87)*x       - we multiply both sides of the equation by x
100=0.58293587705352*x       - we divide both sides of the equation by (0.58293587705352) to get x
100/0.58293587705352=x
171.54545454545=x
x=171.54545454545

now we have:
18.87 is 171.54545454545% of 11
