96.85 is what percent of 643.23 - 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 643.23 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 643.23, so we can write it down as 100%=643.23.
4. We know, that x% equals 96.85 of the output value, so we can write it down as x%=96.85.
5. Now we have two simple equations:
1) 100%=643.23
2) x%=96.85
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%=643.23/96.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 96.85 is what percent of 643.23

100%/x%=643.23/96.85
(100/x)*x=(643.23/96.85)*x       - we multiply both sides of the equation by x
100=6.6415074858028*x       - we divide both sides of the equation by (6.6415074858028) to get x
100/6.6415074858028=x
15.056822598448=x
x=15.056822598448

now we have:
