405.41 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 405.41 of the output value, so we can write it down as x%=405.41.
5. Now we have two simple equations:
1) 100%=4000
2) x%=405.41
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%=4000/405.41
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 405.41 is what percent of 4000

100%/x%=4000/405.41
(100/x)*x=(4000/405.41)*x       - we multiply both sides of the equation by x
100=9.8665548457117*x       - we divide both sides of the equation by (9.8665548457117) to get x
100/9.8665548457117=x
10.13525=x
x=10.13525

now we have:
405.41 is 10.13525% of 4000
