What is 0.0025 percent of 32640 - 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 32640 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 32640 is 100%, so we can write it down as 32640=100%.
4. We know, that x is 0.0025% of the output value, so we can write it down as x=0.0025%.
5. Now we have two simple equations:
1) 32640=100%
2) x=0.0025%
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:
32640/x=100%/0.0025%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.0025% of 32640

32640/x=100/0.0025
(32640/x)*x=(100/0.0025)*x       - we multiply both sides of the equation by x
32640=40000*x       - we divide both sides of the equation by (40000) to get x
32640/40000=x
0.816=x
x=0.816

now we have:
0.0025% of 32640=0.816
