860.13 is what percent of 999 - 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 999 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 999, so we can write it down as 100%=999.
4. We know, that x% equals 860.13 of the output value, so we can write it down as x%=860.13.
5. Now we have two simple equations:
1) 100%=999
2) x%=860.13
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%=999/860.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 860.13 is what percent of 999

100%/x%=999/860.13
(100/x)*x=(999/860.13)*x       - we multiply both sides of the equation by x
100=1.1614523386*x       - we divide both sides of the equation by (1.1614523386) to get x
100/1.1614523386=x
86.099099099099=x
x=86.099099099099

now we have:
860.13 is 86.099099099099% of 999
