200000 is what percent of 5 - 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 5 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 5, so we can write it down as 100%=5.
4. We know, that x% equals 200000 of the output value, so we can write it down as x%=200000.
5. Now we have two simple equations:
1) 100%=5
2) x%=200000
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%=5/200000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 200000 is what percent of 5

100%/x%=5/200000
(100/x)*x=(5/200000)*x       - we multiply both sides of the equation by x
100=2.5E-5*x       - we divide both sides of the equation by (2.5E-5) to get x
100/2.5E-5=x
4000000=x
x=4000000

now we have:
200000 is 4000000% of 5
