115.38 is what percent of 687.1 - 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 687.1 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 687.1, so we can write it down as 100%=687.1.
4. We know, that x% equals 115.38 of the output value, so we can write it down as x%=115.38.
5. Now we have two simple equations:
1) 100%=687.1
2) x%=115.38
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%=687.1/115.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 115.38 is what percent of 687.1

100%/x%=687.1/115.38
(100/x)*x=(687.1/115.38)*x       - we multiply both sides of the equation by x
100=5.9551048708615*x       - we divide both sides of the equation by (5.9551048708615) to get x
100/5.9551048708615=x
16.792315529035=x
x=16.792315529035

now we have:
115.38 is 16.792315529035% of 687.1
