2500000 is what percent of 1 - 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 1 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 1, so we can write it down as 100%=1.
4. We know, that x% equals 2500000 of the output value, so we can write it down as x%=2500000.
5. Now we have two simple equations:
1) 100%=1
2) x%=2500000
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%=1/2500000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2500000 is what percent of 1

100%/x%=1/2500000
(100/x)*x=(1/2500000)*x       - we multiply both sides of the equation by x
100=4.0E-7*x       - we divide both sides of the equation by (4.0E-7) to get x
100/4.0E-7=x
250000000=x
x=250000000

now we have:
2500000 is 250000000% of 1
