28854.72 is what percent of 40000 - 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 40000 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 40000, so we can write it down as 100%=40000.
4. We know, that x% equals 28854.72 of the output value, so we can write it down as x%=28854.72.
5. Now we have two simple equations:
1) 100%=40000
2) x%=28854.72
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%=40000/28854.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28854.72 is what percent of 40000

100%/x%=40000/28854.72
(100/x)*x=(40000/28854.72)*x       - we multiply both sides of the equation by x
100=1.3862550043806*x       - we divide both sides of the equation by (1.3862550043806) to get x
100/1.3862550043806=x
72.1368=x
x=72.1368

now we have:
