What is 18.51 percent of 8.51 - 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 8.51 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 8.51 is 100%, so we can write it down as 8.51=100%.
4. We know, that x is 18.51% of the output value, so we can write it down as x=18.51%.
5. Now we have two simple equations:
1) 8.51=100%
2) x=18.51%
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:
8.51/x=100%/18.51%
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 18.51% of 8.51

8.51/x=100/18.51
(8.51/x)*x=(100/18.51)*x       - we multiply both sides of the equation by x
8.51=5.4024851431659*x       - we divide both sides of the equation by (5.4024851431659) to get x
8.51/5.4024851431659=x
1.575201=x
x=1.575201

now we have:
18.51% of 8.51=1.575201
