What is 1.0E+15 percent of 1000 - 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 1000 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 1000 is 100%, so we can write it down as 1000=100%.
4. We know, that x is 1.0E+15% of the output value, so we can write it down as x=1.0E+15%.
5. Now we have two simple equations:
1) 1000=100%
2) x=1.0E+15%
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:
1000/x=100%/1.0E+15%
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+15% of 1000

1000/x=100/1.0E+15
(1000/x)*x=(100/1.0E+15)*x       - we multiply both sides of the equation by x
1000=1.0E-13*x       - we divide both sides of the equation by (1.0E-13) to get x
1000/1.0E-13=x
1.0E+16=x
x=1.0E+16

now we have:
1.0E+15% of 1000=1.0E+16
