857.4 is what percent of 10000 - 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 10000 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 10000, so we can write it down as 100%=10000.
4. We know, that x% equals 857.4 of the output value, so we can write it down as x%=857.4.
5. Now we have two simple equations:
1) 100%=10000
2) x%=857.4
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%=10000/857.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 857.4 is what percent of 10000

100%/x%=10000/857.4
(100/x)*x=(10000/857.4)*x       - we multiply both sides of the equation by x
100=11.663167716352*x       - we divide both sides of the equation by (11.663167716352) to get x
100/11.663167716352=x
8.574=x
x=8.574

now we have:
857.4 is 8.574% of 10000
