What is 0.9975 percent of 2500000000 - 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 2500000000 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 2500000000 is 100%, so we can write it down as 2500000000=100%.
4. We know, that x is 0.9975% of the output value, so we can write it down as x=0.9975%.
5. Now we have two simple equations:
1) 2500000000=100%
2) x=0.9975%
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:
2500000000/x=100%/0.9975%
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 0.9975% of 2500000000

2500000000/x=100/0.9975
(2500000000/x)*x=(100/0.9975)*x       - we multiply both sides of the equation by x
2500000000=100.25062656642*x       - we divide both sides of the equation by (100.25062656642) to get x
2500000000/100.25062656642=x
24937500=x
x=24937500

now we have:
0.9975% of 2500000000=24937500
