What is 0.03 percent of 13.86 - 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 13.86 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 13.86 is 100%, so we can write it down as 13.86=100%.
4. We know, that x is 0.03% of the output value, so we can write it down as x=0.03%.
5. Now we have two simple equations:
1) 13.86=100%
2) x=0.03%
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:
13.86/x=100%/0.03%
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 0.03% of 13.86

13.86/x=100/0.03
(13.86/x)*x=(100/0.03)*x       - we multiply both sides of the equation by x
13.86=3333.3333333333*x       - we divide both sides of the equation by (3333.3333333333) to get x
13.86/3333.3333333333=x
0.004158=x
x=0.004158

now we have:
0.03% of 13.86=0.004158
