What is 1.0E-7 percent of 105000 - 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 105000 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 105000 is 100%, so we can write it down as 105000=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) 105000=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:
105000/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 105000

105000/x=100/1.0E-7
(105000/x)*x=(100/1.0E-7)*x       - we multiply both sides of the equation by x
105000=1000000000*x       - we divide both sides of the equation by (1000000000) to get x
105000/1000000000=x
0.000105=x
x=0.000105

now we have:
1.0E-7% of 105000=0.000105
