What is 0.28 percent of 25000000000 - 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 25000000000 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 25000000000 is 100%, so we can write it down as 25000000000=100%.
4. We know, that x is 0.28% of the output value, so we can write it down as x=0.28%.
5. Now we have two simple equations:
1) 25000000000=100%
2) x=0.28%
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:
25000000000/x=100%/0.28%
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 0.28% of 25000000000

25000000000/x=100/0.28
(25000000000/x)*x=(100/0.28)*x       - we multiply both sides of the equation by x
25000000000=357.14285714286*x       - we divide both sides of the equation by (357.14285714286) to get x
25000000000/357.14285714286=x
70000000=x
x=70000000

now we have:
0.28% of 25000000000=70000000
