256000000 is what percent of 2 - 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 2 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 100% equals 2, so we can write it down as 100%=2.
4. We know, that x% equals 256000000 of the output value, so we can write it down as x%=256000000.
5. Now we have two simple equations:
1) 100%=2
2) x%=256000000
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:
100%/x%=2/256000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 256000000 is what percent of 2

100%/x%=2/256000000
(100/x)*x=(2/256000000)*x       - we multiply both sides of the equation by x
100=7.8125E-9*x       - we divide both sides of the equation by (7.8125E-9) to get x
100/7.8125E-9=x
12800000000=x
x=12800000000

now we have:
256000000 is 12800000000% of 2
