What is 25000000 percent of 4000 - 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 4000 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 4000 is 100%, so we can write it down as 4000=100%.
4. We know, that x is 25000000% of the output value, so we can write it down as x=25000000%.
5. Now we have two simple equations:
1) 4000=100%
2) x=25000000%
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:
4000/x=100%/25000000%
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 25000000% of 4000

4000/x=100/25000000
(4000/x)*x=(100/25000000)*x       - we multiply both sides of the equation by x
4000=4.0E-6*x       - we divide both sides of the equation by (4.0E-6) to get x
4000/4.0E-6=x
1000000000=x
x=1000000000

now we have:
25000000% of 4000=1000000000
