81000 is what percent of 8 - 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 8 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 8, so we can write it down as 100%=8.
4. We know, that x% equals 81000 of the output value, so we can write it down as x%=81000.
5. Now we have two simple equations:
1) 100%=8
2) x%=81000
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%=8/81000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81000 is what percent of 8

100%/x%=8/81000
(100/x)*x=(8/81000)*x       - we multiply both sides of the equation by x
100=9.8765432098765E-5*x       - we divide both sides of the equation by (9.8765432098765E-5) to get x
100/9.8765432098765E-5=x
1012500=x
x=1012500

now we have:
81000 is 1012500% of 8
