What is 0.04 percent of 0.025 - 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 0.025 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 0.025 is 100%, so we can write it down as 0.025=100%.
4. We know, that x is 0.04% of the output value, so we can write it down as x=0.04%.
5. Now we have two simple equations:
1) 0.025=100%
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:
0.025/x=100%/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 what is 0.04% of 0.025

0.025/x=100/0.04
(0.025/x)*x=(100/0.04)*x       - we multiply both sides of the equation by x
0.025=2500*x       - we divide both sides of the equation by (2500) to get x
0.025/2500=x
1.0E-5=x
x=1.0E-5

now we have:
0.04% of 0.025=1.0E-5
