What is 0.25 percent of 7000000000 - 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 7000000000 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 7000000000 is 100%, so we can write it down as 7000000000=100%.
4. We know, that x is 0.25% of the output value, so we can write it down as x=0.25%.
5. Now we have two simple equations:
1) 7000000000=100%
2) x=0.25%
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:
7000000000/x=100%/0.25%
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 0.25% of 7000000000

7000000000/x=100/0.25
(7000000000/x)*x=(100/0.25)*x       - we multiply both sides of the equation by x
7000000000=400*x       - we divide both sides of the equation by (400) to get x
7000000000/400=x
17500000=x
x=17500000

now we have:
0.25% of 7000000000=17500000
