What is 9.9E+99 percent of 9.9E-99 - 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 9.9E-99 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 9.9E-99 is 100%, so we can write it down as 9.9E-99=100%.
4. We know, that x is 9.9E+99% of the output value, so we can write it down as x=9.9E+99%.
5. Now we have two simple equations:
1) 9.9E-99=100%
2) x=9.9E+99%
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:
9.9E-99/x=100%/9.9E+99%
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 9.9E+99% of 9.9E-99

9.9E-99/x=100/9.9E+99
(9.9E-99/x)*x=(100/9.9E+99)*x       - we multiply both sides of the equation by x
9.9E-99=1.010101010101E-98*x       - we divide both sides of the equation by (1.010101010101E-98) to get x
9.9E-99/1.010101010101E-98=x
0.9801=x
x=0.9801

now we have:
9.9E+99% of 9.9E-99=0.9801
