What is 99.999999999 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 99.999999999% of the output value, so we can write it down as x=99.999999999%.
5. Now we have two simple equations:
1) 1=100%
2) x=99.999999999%
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%/99.999999999%
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 99.999999999% of 1

1/x=100/99.999999999
(1/x)*x=(100/99.999999999)*x       - we multiply both sides of the equation by x
1=1.00000000001*x       - we divide both sides of the equation by (1.00000000001) to get x
1/1.00000000001=x
0.99999999999=x
x=0.99999999999

now we have:
99.999999999% of 1=0.99999999999
