8.5 is what percent of 215000 - 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 215000 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 215000, so we can write it down as 100%=215000.
4. We know, that x% equals 8.5 of the output value, so we can write it down as x%=8.5.
5. Now we have two simple equations:
1) 100%=215000
2) x%=8.5
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%=215000/8.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.5 is what percent of 215000

100%/x%=215000/8.5
(100/x)*x=(215000/8.5)*x       - we multiply both sides of the equation by x
100=25294.117647059*x       - we divide both sides of the equation by (25294.117647059) to get x
100/25294.117647059=x
0.003953488372093=x
x=0.003953488372093

now we have:
8.5 is 0.003953488372093% of 215000
