What is 7.777 percent of 9000000000 - 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 9000000000 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 9000000000 is 100%, so we can write it down as 9000000000=100%.
4. We know, that x is 7.777% of the output value, so we can write it down as x=7.777%.
5. Now we have two simple equations:
1) 9000000000=100%
2) x=7.777%
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:
9000000000/x=100%/7.777%
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 7.777% of 9000000000

9000000000/x=100/7.777
(9000000000/x)*x=(100/7.777)*x       - we multiply both sides of the equation by x
9000000000=12.858428700013*x       - we divide both sides of the equation by (12.858428700013) to get x
9000000000/12.858428700013=x
699930000=x
x=699930000

now we have:
7.777% of 9000000000=699930000
