8383838 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 8383838 of the output value, so we can write it down as x%=8383838.
5. Now we have two simple equations:
1) 100%=1.0E+18
2) x%=8383838
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+18/8383838
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8383838 is what percent of 1.0E+18

100%/x%=1.0E+18/8383838
(100/x)*x=(1.0E+18/8383838)*x       - we multiply both sides of the equation by x
100=119277113894.61*x       - we divide both sides of the equation by (119277113894.61) to get x
100/119277113894.61=x
8.383838E-10=x
x=8.383838E-10

now we have:
8383838 is 8.383838E-10% of 1.0E+18
