What is 3.99 percent of 0.25 - 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 0.25 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 0.25 is 100%, so we can write it down as 0.25=100%.
4. We know, that x is 3.99% of the output value, so we can write it down as x=3.99%.
5. Now we have two simple equations:
1) 0.25=100%
2) x=3.99%
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:
0.25/x=100%/3.99%
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 3.99% of 0.25

0.25/x=100/3.99
(0.25/x)*x=(100/3.99)*x       - we multiply both sides of the equation by x
0.25=25.062656641604*x       - we divide both sides of the equation by (25.062656641604) to get x
0.25/25.062656641604=x
0.009975=x
x=0.009975

now we have:
3.99% of 0.25=0.009975
