8.6 is what percent of 125 - 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 125 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 125, so we can write it down as 100%=125.
4. We know, that x% equals 8.6 of the output value, so we can write it down as x%=8.6.
5. Now we have two simple equations:
1) 100%=125
2) x%=8.6
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%=125/8.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.6 is what percent of 125

100%/x%=125/8.6
(100/x)*x=(125/8.6)*x       - we multiply both sides of the equation by x
100=14.53488372093*x       - we divide both sides of the equation by (14.53488372093) to get x
100/14.53488372093=x
6.88=x
x=6.88

now we have:
8.6 is 6.88% of 125
