What is 20.15 percent of 28.57 - 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 28.57 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 28.57 is 100%, so we can write it down as 28.57=100%.
4. We know, that x is 20.15% of the output value, so we can write it down as x=20.15%.
5. Now we have two simple equations:
1) 28.57=100%
2) x=20.15%
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:
28.57/x=100%/20.15%
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 20.15% of 28.57

28.57/x=100/20.15
(28.57/x)*x=(100/20.15)*x       - we multiply both sides of the equation by x
28.57=4.9627791563275*x       - we divide both sides of the equation by (4.9627791563275) to get x
28.57/4.9627791563275=x
5.756855=x
x=5.756855

now we have:
20.15% of 28.57=5.756855
