What is 900000 percent of 90000000 - 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 90000000 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 90000000 is 100%, so we can write it down as 90000000=100%.
4. We know, that x is 900000% of the output value, so we can write it down as x=900000%.
5. Now we have two simple equations:
1) 90000000=100%
2) x=900000%
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:
90000000/x=100%/900000%
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 900000% of 90000000

90000000/x=100/900000
(90000000/x)*x=(100/900000)*x       - we multiply both sides of the equation by x
90000000=0.00011111111111111*x       - we divide both sides of the equation by (0.00011111111111111) to get x
90000000/0.00011111111111111=x
810000000000=x
x=810000000000

now we have:
900000% of 90000000=810000000000
