What is 2500000 percent of 28000000 - 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 28000000 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 28000000 is 100%, so we can write it down as 28000000=100%.
4. We know, that x is 2500000% of the output value, so we can write it down as x=2500000%.
5. Now we have two simple equations:
1) 28000000=100%
2) x=2500000%
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:
28000000/x=100%/2500000%
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 2500000% of 28000000

28000000/x=100/2500000
(28000000/x)*x=(100/2500000)*x       - we multiply both sides of the equation by x
28000000=4.0E-5*x       - we divide both sides of the equation by (4.0E-5) to get x
28000000/4.0E-5=x
700000000000=x
x=700000000000

now we have:
2500000% of 28000000=700000000000
