What is 8000000 percent of 0.9 - 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 0.9 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 0.9 is 100%, so we can write it down as 0.9=100%.
4. We know, that x is 8000000% of the output value, so we can write it down as x=8000000%.
5. Now we have two simple equations:
1) 0.9=100%
2) x=8000000%
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:
0.9/x=100%/8000000%
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 8000000% of 0.9

0.9/x=100/8000000
(0.9/x)*x=(100/8000000)*x       - we multiply both sides of the equation by x
0.9=1.25E-5*x       - we divide both sides of the equation by (1.25E-5) to get x
0.9/1.25E-5=x
72000=x
x=72000

now we have:
8000000% of 0.9=72000
