518.4 is what percent of 432000000000 - 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 432000000000 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 432000000000, so we can write it down as 100%=432000000000.
4. We know, that x% equals 518.4 of the output value, so we can write it down as x%=518.4.
5. Now we have two simple equations:
1) 100%=432000000000
2) x%=518.4
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%=432000000000/518.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 518.4 is what percent of 432000000000

100%/x%=432000000000/518.4
(100/x)*x=(432000000000/518.4)*x       - we multiply both sides of the equation by x
100=833333333.33333*x       - we divide both sides of the equation by (833333333.33333) to get x
100/833333333.33333=x
1.2E-7=x
x=1.2E-7

now we have:
518.4 is 1.2E-7% of 432000000000
