8439.48 is what percent of 10500 - 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 10500 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 100% equals 10500, so we can write it down as 100%=10500.
4. We know, that x% equals 8439.48 of the output value, so we can write it down as x%=8439.48.
5. Now we have two simple equations:
1) 100%=10500
2) x%=8439.48
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:
100%/x%=10500/8439.48
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8439.48 is what percent of 10500

100%/x%=10500/8439.48
(100/x)*x=(10500/8439.48)*x       - we multiply both sides of the equation by x
100=1.2441524833284*x       - we divide both sides of the equation by (1.2441524833284) to get x
100/1.2441524833284=x
80.376=x
x=80.376

now we have:
