What is 18.9 percent of 87.6 - 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 87.6 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 87.6 is 100%, so we can write it down as 87.6=100%.
4. We know, that x is 18.9% of the output value, so we can write it down as x=18.9%.
5. Now we have two simple equations:
1) 87.6=100%
2) x=18.9%
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:
87.6/x=100%/18.9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 18.9% of 87.6

87.6/x=100/18.9
(87.6/x)*x=(100/18.9)*x       - we multiply both sides of the equation by x
87.6=5.2910052910053*x       - we divide both sides of the equation by (5.2910052910053) to get x
87.6/5.2910052910053=x
16.5564=x
x=16.5564

now we have:
18.9% of 87.6=16.5564
