What is 2.55E-20 percent of 1339400000 - 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 1339400000 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 1339400000 is 100%, so we can write it down as 1339400000=100%.
4. We know, that x is 2.55E-20% of the output value, so we can write it down as x=2.55E-20%.
5. Now we have two simple equations:
1) 1339400000=100%
2) x=2.55E-20%
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:
1339400000/x=100%/2.55E-20%
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 2.55E-20% of 1339400000

1339400000/x=100/2.55E-20
(1339400000/x)*x=(100/2.55E-20)*x       - we multiply both sides of the equation by x
1339400000=3.921568627451E+21*x       - we divide both sides of the equation by (3.921568627451E+21) to get x
1339400000/3.921568627451E+21=x
3.41547E-13=x
x=3.41547E-13

now we have:
2.55E-20% of 1339400000=3.41547E-13
