What is 48.15 percent of 15 - 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 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 is 100%, so we can write it down as 15=100%.
4. We know, that x is 48.15% of the output value, so we can write it down as x=48.15%.
5. Now we have two simple equations:
1) 15=100%
2) x=48.15%
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:
15/x=100%/48.15%
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 48.15% of 15

15/x=100/48.15
(15/x)*x=(100/48.15)*x       - we multiply both sides of the equation by x
15=2.0768431983385*x       - we divide both sides of the equation by (2.0768431983385) to get x
15/2.0768431983385=x
7.2225=x
x=7.2225

now we have:
48.15% of 15=7.2225
