What is 9999999999 percent of 1 - 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 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 1 is 100%, so we can write it down as 1=100%.
4. We know, that x is 9999999999% of the output value, so we can write it down as x=9999999999%.
5. Now we have two simple equations:
1) 1=100%
2) x=9999999999%
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:
1/x=100%/9999999999%
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 9999999999% of 1

1/x=100/9999999999
(1/x)*x=(100/9999999999)*x       - we multiply both sides of the equation by x
1=1.0000000001E-8*x       - we divide both sides of the equation by (1.0000000001E-8) to get x
1/1.0000000001E-8=x
99999999.99=x
x=99999999.99

now we have:
9999999999% of 1=99999999.99
