285.28 is what percent of 4000 - 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 4000 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 4000, so we can write it down as 100%=4000.
4. We know, that x% equals 285.28 of the output value, so we can write it down as x%=285.28.
5. Now we have two simple equations:
1) 100%=4000
2) x%=285.28
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%=4000/285.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 285.28 is what percent of 4000

100%/x%=4000/285.28
(100/x)*x=(4000/285.28)*x       - we multiply both sides of the equation by x
100=14.02131239484*x       - we divide both sides of the equation by (14.02131239484) to get x
100/14.02131239484=x
7.132=x
x=7.132

now we have:
285.28 is 7.132% of 4000
