What is 1.0E+30 percent of 9999999999 - 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 9999999999 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 9999999999 is 100%, so we can write it down as 9999999999=100%.
4. We know, that x is 1.0E+30% of the output value, so we can write it down as x=1.0E+30%.
5. Now we have two simple equations:
1) 9999999999=100%
2) x=1.0E+30%
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:
9999999999/x=100%/1.0E+30%
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+30% of 9999999999

9999999999/x=100/1.0E+30
(9999999999/x)*x=(100/1.0E+30)*x       - we multiply both sides of the equation by x
9999999999=1.0E-28*x       - we divide both sides of the equation by (1.0E-28) to get x
9999999999/1.0E-28=x
9.999999999E+37=x
x=9.999999999E+37

now we have:
1.0E+30% of 9999999999=9.999999999E+37
