What is 3.0E-5 percent of 2.0E+19 - 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 2.0E+19 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 2.0E+19 is 100%, so we can write it down as 2.0E+19=100%.
4. We know, that x is 3.0E-5% of the output value, so we can write it down as x=3.0E-5%.
5. Now we have two simple equations:
1) 2.0E+19=100%
2) x=3.0E-5%
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:
2.0E+19/x=100%/3.0E-5%
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 3.0E-5% of 2.0E+19

2.0E+19/x=100/3.0E-5
(2.0E+19/x)*x=(100/3.0E-5)*x       - we multiply both sides of the equation by x
2.0E+19=3333333.3333333*x       - we divide both sides of the equation by (3333333.3333333) to get x
2.0E+19/3333333.3333333=x
6000000000000=x
x=6000000000000

now we have:
3.0E-5% of 2.0E+19=6000000000000
