410000000 is what percent of 1.0E+18 - 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 1.0E+18 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 1.0E+18, so we can write it down as 100%=1.0E+18.
4. We know, that x% equals 410000000 of the output value, so we can write it down as x%=410000000.
5. Now we have two simple equations:
1) 100%=1.0E+18
2) x%=410000000
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%=1.0E+18/410000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 410000000 is what percent of 1.0E+18

100%/x%=1.0E+18/410000000
(100/x)*x=(1.0E+18/410000000)*x       - we multiply both sides of the equation by x
100=2439024390.2439*x       - we divide both sides of the equation by (2439024390.2439) to get x
100/2439024390.2439=x
4.1E-8=x
x=4.1E-8

now we have:
410000000 is 4.1E-8% of 1.0E+18
