8.85 is what percent of 2815 - 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 2815 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 2815, so we can write it down as 100%=2815.
4. We know, that x% equals 8.85 of the output value, so we can write it down as x%=8.85.
5. Now we have two simple equations:
1) 100%=2815
2) x%=8.85
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%=2815/8.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.85 is what percent of 2815

100%/x%=2815/8.85
(100/x)*x=(2815/8.85)*x       - we multiply both sides of the equation by x
100=318.0790960452*x       - we divide both sides of the equation by (318.0790960452) to get x
100/318.0790960452=x
0.31438721136767=x
x=0.31438721136767

now we have:
8.85 is 0.31438721136767% of 2815
