What is 8.15 percent of 252.4 - 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 252.4 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 252.4 is 100%, so we can write it down as 252.4=100%.
4. We know, that x is 8.15% of the output value, so we can write it down as x=8.15%.
5. Now we have two simple equations:
1) 252.4=100%
2) x=8.15%
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:
252.4/x=100%/8.15%
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 8.15% of 252.4

252.4/x=100/8.15
(252.4/x)*x=(100/8.15)*x       - we multiply both sides of the equation by x
252.4=12.269938650307*x       - we divide both sides of the equation by (12.269938650307) to get x
252.4/12.269938650307=x
20.5706=x
x=20.5706

now we have:
8.15% of 252.4=20.5706
