What is 7700 percent of 7000000000 - 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 7000000000 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 7000000000 is 100%, so we can write it down as 7000000000=100%.
4. We know, that x is 7700% of the output value, so we can write it down as x=7700%.
5. Now we have two simple equations:
1) 7000000000=100%
2) x=7700%
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:
7000000000/x=100%/7700%
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 7700% of 7000000000

7000000000/x=100/7700
(7000000000/x)*x=(100/7700)*x       - we multiply both sides of the equation by x
7000000000=0.012987012987013*x       - we divide both sides of the equation by (0.012987012987013) to get x
7000000000/0.012987012987013=x
539000000000=x
x=539000000000

now we have:
7700% of 7000000000=539000000000
