0.02 is what percent of 80000 - 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 80000 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 80000, so we can write it down as 100%=80000.
4. We know, that x% equals 0.02 of the output value, so we can write it down as x%=0.02.
5. Now we have two simple equations:
1) 100%=80000
2) x%=0.02
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%=80000/0.02
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.02 is what percent of 80000

100%/x%=80000/0.02
(100/x)*x=(80000/0.02)*x       - we multiply both sides of the equation by x
100=4000000*x       - we divide both sides of the equation by (4000000) to get x
100/4000000=x
2.5E-5=x
x=2.5E-5

now we have:
0.02 is 2.5E-5% of 80000
