845.1 is what percent of 865 - 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 865 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 865, so we can write it down as 100%=865.
4. We know, that x% equals 845.1 of the output value, so we can write it down as x%=845.1.
5. Now we have two simple equations:
1) 100%=865
2) x%=845.1
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%=865/845.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 845.1 is what percent of 865

100%/x%=865/845.1
(100/x)*x=(865/845.1)*x       - we multiply both sides of the equation by x
100=1.0235475091705*x       - we divide both sides of the equation by (1.0235475091705) to get x
100/1.0235475091705=x
97.699421965318=x
x=97.699421965318

now we have:
845.1 is 97.699421965318% of 865
