What is 8.425 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 8.425% of the output value, so we can write it down as x=8.425%.
5. Now we have two simple equations:
1) 15=100%
2) x=8.425%
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%/8.425%
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 8.425% of 15

15/x=100/8.425
(15/x)*x=(100/8.425)*x       - we multiply both sides of the equation by x
15=11.86943620178*x       - we divide both sides of the equation by (11.86943620178) to get x
15/11.86943620178=x
1.26375=x
x=1.26375

now we have:
8.425% of 15=1.26375
