What is 900 percent of 800000000 - 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 800000000 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 800000000 is 100%, so we can write it down as 800000000=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 800000000=100%
2) x=900%
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:
800000000/x=100%/900%
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 900% of 800000000

800000000/x=100/900
(800000000/x)*x=(100/900)*x       - we multiply both sides of the equation by x
800000000=0.11111111111111*x       - we divide both sides of the equation by (0.11111111111111) to get x
800000000/0.11111111111111=x
7200000000=x
x=7200000000

now we have:
900% of 800000000=7200000000
