What is 2000000000 percent of 2800 - 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 2800 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 2800 is 100%, so we can write it down as 2800=100%.
4. We know, that x is 2000000000% of the output value, so we can write it down as x=2000000000%.
5. Now we have two simple equations:
1) 2800=100%
2) x=2000000000%
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:
2800/x=100%/2000000000%
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 2000000000% of 2800

2800/x=100/2000000000
(2800/x)*x=(100/2000000000)*x       - we multiply both sides of the equation by x
2800=5.0E-8*x       - we divide both sides of the equation by (5.0E-8) to get x
2800/5.0E-8=x
56000000000=x
x=56000000000

now we have:
2000000000% of 2800=56000000000
