What is 2.505 percent of 0.5 - 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 0.5 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 0.5 is 100%, so we can write it down as 0.5=100%.
4. We know, that x is 2.505% of the output value, so we can write it down as x=2.505%.
5. Now we have two simple equations:
1) 0.5=100%
2) x=2.505%
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:
0.5/x=100%/2.505%
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 2.505% of 0.5

0.5/x=100/2.505
(0.5/x)*x=(100/2.505)*x       - we multiply both sides of the equation by x
0.5=39.920159680639*x       - we divide both sides of the equation by (39.920159680639) to get x
0.5/39.920159680639=x
0.012525=x
x=0.012525

now we have:
2.505% of 0.5=0.012525
