What is 1.3E-8 percent of 7753000000 - 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 7753000000 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 7753000000 is 100%, so we can write it down as 7753000000=100%.
4. We know, that x is 1.3E-8% of the output value, so we can write it down as x=1.3E-8%.
5. Now we have two simple equations:
1) 7753000000=100%
2) x=1.3E-8%
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:
7753000000/x=100%/1.3E-8%
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 1.3E-8% of 7753000000

7753000000/x=100/1.3E-8
(7753000000/x)*x=(100/1.3E-8)*x       - we multiply both sides of the equation by x
7753000000=7692307692.3077*x       - we divide both sides of the equation by (7692307692.3077) to get x
7753000000/7692307692.3077=x
1.00789=x
x=1.00789

now we have:
1.3E-8% of 7753000000=1.00789
