What is 6.8E-9 percent of 3800000000 - 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 3800000000 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 3800000000 is 100%, so we can write it down as 3800000000=100%.
4. We know, that x is 6.8E-9% of the output value, so we can write it down as x=6.8E-9%.
5. Now we have two simple equations:
1) 3800000000=100%
2) x=6.8E-9%
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:
3800000000/x=100%/6.8E-9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 6.8E-9% of 3800000000

3800000000/x=100/6.8E-9
(3800000000/x)*x=(100/6.8E-9)*x       - we multiply both sides of the equation by x
3800000000=14705882352.941*x       - we divide both sides of the equation by (14705882352.941) to get x
3800000000/14705882352.941=x
0.2584=x
x=0.2584

now we have:
6.8E-9% of 3800000000=0.2584
