What is 28.08 percent of 15.4 - 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 15.4 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 15.4 is 100%, so we can write it down as 15.4=100%.
4. We know, that x is 28.08% of the output value, so we can write it down as x=28.08%.
5. Now we have two simple equations:
1) 15.4=100%
2) x=28.08%
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:
15.4/x=100%/28.08%
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 28.08% of 15.4

15.4/x=100/28.08
(15.4/x)*x=(100/28.08)*x       - we multiply both sides of the equation by x
15.4=3.5612535612536*x       - we divide both sides of the equation by (3.5612535612536) to get x
15.4/3.5612535612536=x
4.32432=x
x=4.32432

now we have:
28.08% of 15.4=4.32432
