800000 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 800000 of the output value, so we can write it down as x%=800000.
5. Now we have two simple equations:
1) 100%=2
2) x%=800000
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%=2/800000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 800000 is what percent of 2

100%/x%=2/800000
(100/x)*x=(2/800000)*x       - we multiply both sides of the equation by x
100=2.5E-6*x       - we divide both sides of the equation by (2.5E-6) to get x
100/2.5E-6=x
40000000=x
x=40000000

now we have:
800000 is 40000000% of 2
