What is 15.2 percent of 28 - 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 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 is 100%, so we can write it down as 28=100%.
4. We know, that x is 15.2% of the output value, so we can write it down as x=15.2%.
5. Now we have two simple equations:
1) 28=100%
2) x=15.2%
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/x=100%/15.2%
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 15.2% of 28

28/x=100/15.2
(28/x)*x=(100/15.2)*x       - we multiply both sides of the equation by x
28=6.5789473684211*x       - we divide both sides of the equation by (6.5789473684211) to get x
28/6.5789473684211=x
4.256=x
x=4.256

now we have:
15.2% of 28=4.256
