80 is what percent of 8000000 - 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 8000000 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 8000000, so we can write it down as 100%=8000000.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=8000000
2) x%=80
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%=8000000/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 8000000

100%/x%=8000000/80
(100/x)*x=(8000000/80)*x       - we multiply both sides of the equation by x
100=100000*x       - we divide both sides of the equation by (100000) to get x
100/100000=x
0.001=x
x=0.001

now we have:
80 is 0.001% of 8000000
