What is 17.81 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 17.81% of the output value, so we can write it down as x=17.81%.
5. Now we have two simple equations:
1) 15=100%
2) x=17.81%
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%/17.81%
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 17.81% of 15

15/x=100/17.81
(15/x)*x=(100/17.81)*x       - we multiply both sides of the equation by x
15=5.6148231330713*x       - we divide both sides of the equation by (5.6148231330713) to get x
15/5.6148231330713=x
2.6715=x
x=2.6715

now we have:
17.81% of 15=2.6715
