What is 1.0E-7 percent of 3500000000 - 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 3500000000 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 3500000000 is 100%, so we can write it down as 3500000000=100%.
4. We know, that x is 1.0E-7% of the output value, so we can write it down as x=1.0E-7%.
5. Now we have two simple equations:
1) 3500000000=100%
2) x=1.0E-7%
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:
3500000000/x=100%/1.0E-7%
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 1.0E-7% of 3500000000

3500000000/x=100/1.0E-7
(3500000000/x)*x=(100/1.0E-7)*x       - we multiply both sides of the equation by x
3500000000=1000000000*x       - we divide both sides of the equation by (1000000000) to get x
3500000000/1000000000=x
3.5=x
x=3.5

now we have:
1.0E-7% of 3500000000=3.5
