What is 250000000 percent of 80000000000 - 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 80000000000 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 80000000000 is 100%, so we can write it down as 80000000000=100%.
4. We know, that x is 250000000% of the output value, so we can write it down as x=250000000%.
5. Now we have two simple equations:
1) 80000000000=100%
2) x=250000000%
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:
80000000000/x=100%/250000000%
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 250000000% of 80000000000

80000000000/x=100/250000000
(80000000000/x)*x=(100/250000000)*x       - we multiply both sides of the equation by x
80000000000=4.0E-7*x       - we divide both sides of the equation by (4.0E-7) to get x
80000000000/4.0E-7=x
2.0E+17=x
x=2.0E+17

now we have:
250000000% of 80000000000=2.0E+17
