What is 7.0E-7 percent of 22500000 - 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 22500000 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 22500000 is 100%, so we can write it down as 22500000=100%.
4. We know, that x is 7.0E-7% of the output value, so we can write it down as x=7.0E-7%.
5. Now we have two simple equations:
1) 22500000=100%
2) x=7.0E-7%
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:
22500000/x=100%/7.0E-7%
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 7.0E-7% of 22500000

22500000/x=100/7.0E-7
(22500000/x)*x=(100/7.0E-7)*x       - we multiply both sides of the equation by x
22500000=142857142.85714*x       - we divide both sides of the equation by (142857142.85714) to get x
22500000/142857142.85714=x
0.1575=x
x=0.1575

now we have:
7.0E-7% of 22500000=0.1575
