What is 1.0E+80 percent of 99999 - 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 99999 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 99999 is 100%, so we can write it down as 99999=100%.
4. We know, that x is 1.0E+80% of the output value, so we can write it down as x=1.0E+80%.
5. Now we have two simple equations:
1) 99999=100%
2) x=1.0E+80%
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:
99999/x=100%/1.0E+80%
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+80% of 99999

99999/x=100/1.0E+80
(99999/x)*x=(100/1.0E+80)*x       - we multiply both sides of the equation by x
99999=1.0E-78*x       - we divide both sides of the equation by (1.0E-78) to get x
99999/1.0E-78=x
9.9999E+82=x
x=9.9999E+82

now we have:
1.0E+80% of 99999=9.9999E+82
