What is 9000000 percent of 1.0E+17 - 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 1.0E+17 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 1.0E+17 is 100%, so we can write it down as 1.0E+17=100%.
4. We know, that x is 9000000% of the output value, so we can write it down as x=9000000%.
5. Now we have two simple equations:
1) 1.0E+17=100%
2) x=9000000%
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:
1.0E+17/x=100%/9000000%
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 9000000% of 1.0E+17

1.0E+17/x=100/9000000
(1.0E+17/x)*x=(100/9000000)*x       - we multiply both sides of the equation by x
1.0E+17=1.1111111111111E-5*x       - we divide both sides of the equation by (1.1111111111111E-5) to get x
1.0E+17/1.1111111111111E-5=x
9.0E+21=x
x=9.0E+21

now we have:
9000000% of 1.0E+17=9.0E+21
