40.4 is what percent of 10540.4 - 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 10540.4 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 10540.4, so we can write it down as 100%=10540.4.
4. We know, that x% equals 40.4 of the output value, so we can write it down as x%=40.4.
5. Now we have two simple equations:
1) 100%=10540.4
2) x%=40.4
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%=10540.4/40.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.4 is what percent of 10540.4

100%/x%=10540.4/40.4
(100/x)*x=(10540.4/40.4)*x       - we multiply both sides of the equation by x
100=260.90099009901*x       - we divide both sides of the equation by (260.90099009901) to get x
100/260.90099009901=x
0.38328716177754=x
x=0.38328716177754

now we have:
40.4 is 0.38328716177754% of 10540.4
