30.16 is what percent of 315 - 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 315 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 315, so we can write it down as 100%=315.
4. We know, that x% equals 30.16 of the output value, so we can write it down as x%=30.16.
5. Now we have two simple equations:
1) 100%=315
2) x%=30.16
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%=315/30.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.16 is what percent of 315

100%/x%=315/30.16
(100/x)*x=(315/30.16)*x       - we multiply both sides of the equation by x
100=10.444297082228*x       - we divide both sides of the equation by (10.444297082228) to get x
100/10.444297082228=x
9.5746031746032=x
x=9.5746031746032

now we have:
30.16 is 9.5746031746032% of 315
