What is 6.39 percent of 10509 - 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 10509 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 10509 is 100%, so we can write it down as 10509=100%.
4. We know, that x is 6.39% of the output value, so we can write it down as x=6.39%.
5. Now we have two simple equations:
1) 10509=100%
2) x=6.39%
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:
10509/x=100%/6.39%
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 6.39% of 10509

10509/x=100/6.39
(10509/x)*x=(100/6.39)*x       - we multiply both sides of the equation by x
10509=15.649452269171*x       - we divide both sides of the equation by (15.649452269171) to get x
10509/15.649452269171=x
671.5251=x
x=671.5251

now we have:
6.39% of 10509=671.5251
