0.04 is what percent of 8500 - 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 8500 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 8500, so we can write it down as 100%=8500.
4. We know, that x% equals 0.04 of the output value, so we can write it down as x%=0.04.
5. Now we have two simple equations:
1) 100%=8500
2) x%=0.04
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%=8500/0.04
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.04 is what percent of 8500

100%/x%=8500/0.04
(100/x)*x=(8500/0.04)*x       - we multiply both sides of the equation by x
100=212500*x       - we divide both sides of the equation by (212500) to get x
100/212500=x
0.00047058823529412=x
x=0.00047058823529412

now we have:
0.04 is 0.00047058823529412% of 8500
