What is 4500000000 percent of 250 - 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 250 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 250 is 100%, so we can write it down as 250=100%.
4. We know, that x is 4500000000% of the output value, so we can write it down as x=4500000000%.
5. Now we have two simple equations:
1) 250=100%
2) x=4500000000%
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:
250/x=100%/4500000000%
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 4500000000% of 250

250/x=100/4500000000
(250/x)*x=(100/4500000000)*x       - we multiply both sides of the equation by x
250=2.2222222222222E-8*x       - we divide both sides of the equation by (2.2222222222222E-8) to get x
250/2.2222222222222E-8=x
11250000000=x
x=11250000000

now we have:
4500000000% of 250=11250000000
